Knitting in the round lets you make seamless things like hats, cowls, and sleeves. You don’t have to sew pieces together, which is honestly a relief.
It might look tricky at first, but once you get the hang of it, it’s one of the most satisfying ways to knit. You knit in a continuous circle using circular or double-pointed needles, and you get a smooth, tube-like fabric.
You’ll need the right tools and yarn, then you cast on and join your stitches without twisting them. There are a few methods—short circular needles, double-pointed needles, or the magic loop—for different projects.
Each method helps you knit comfortably and get neat, even results. Once you get the basics, you’ll be able to make everything from cozy beanies to seamless sweaters.

Essential Tools and Materials
You really just need a few key tools to knit in the round. The right circular needles, yarn, and a couple of small things like stitch markers make it all easier.
Choosing the Right Circular Needles
Your circular needles are the main thing you’ll use. They come in different lengths and materials, so pick what works for your project.
For hats or sleeves, go for a short cable, maybe 16 inches. For bigger projects like sweaters, you’ll want a longer cable, 24–40 inches.
Needle tips might be metal, wood, or plastic. Metal is fast, wood is grippier and good for beginners. If your project is too small for circulars, grab some double-pointed needles (DPNs) so your stitches don’t stretch out.

Suggested Needle Length |
|

16 in (40 cm) |
|
Sweater body |
32–40 in (80–100 cm) |
|
Socks |
9–12 in (23–30 cm) or DPNs |
Make sure your needle size matches your yarn weight. Knit a small gauge swatch to check your tension—it really does help.
Selecting Yarn for Circular Knitting
Pick yarn that matches your project’s feel. Smooth, medium-weight yarns like worsted or DK are easier to use when you’re just starting out.
Stay away from fuzzy or slippery yarns until you’re more comfortable. Wool has some stretch, so it helps your stitches stay even, while cotton and acrylic don’t stretch much.
If you’re using DPNs or small circulars, choose a yarn that won’t split easily. Always check the label for the recommended needle size to keep your stitches even.
Stitch Markers and Accessories
A stitch marker marks the start of each round. Pop one between the first and last stitch when you join your cast-on.
Other handy things: row counters, tapestry needles, and scissors. Row counters help track rounds, and tapestry needles are for weaving in ends.
Keep your tools in a small bag or box. If you’re using multiple DPNs, different colored needles or extra markers can help keep things organized.

Casting On for Knitting in the Round
When you start, you cast on your stitches and connect them into a circle. The way you do this affects how neat your project looks.
Popular Cast On Methods
There are a few ways to cast on for knitting in the round. The long-tail cast on is the most popular because it gives you a stretchy, even edge.
The cable cast on makes a firmer edge, which is good for cuffs. If you like DPNs, divide your stitches evenly before joining.
For circular needles, slide the stitches onto the cable so they’re not too tight. The magic loop method works for small projects using a long circular needle.
Always start with a slip knot and cast on the number of stitches your pattern asks for. Try out different methods and see which one feels best.
Avoiding Twists in Your Cast On
Twisted stitches can mess up your project. Before joining, lay your cast-on stitches flat on the needle with the cast on edge facing the same way all the way around.
Run your finger along the edge to check. If the edge flips or crosses, fix it before you join. If you join with a twist, you’ll have to start over.
To join, bring the working yarn from the last cast-on stitch to the first and knit across. Some people add an extra stitch and knit the first and last together to close the gap.
Calculating the Number of Stitches
Getting the right number of cast on stitches is important for fit. Use your pattern’s gauge to figure out how many stitches per inch you need.
|
Measurement |
Gauge |
Stitches to Cast On |
|
20-inch hat |
5 stitches per inch |
100 stitches |
If you’re making up your own project, measure your swatch and multiply the stitches per inch by the size you want. Round to a number that fits your stitch pattern, like multiples of 4 for ribbing.
Double-check your math before you start. Just a few extra or missing stitches can change the size a lot.

Joining and Beginning to Knit in the Round
You connect your cast-on stitches into a circle, mark the start of each round, and knit the first rounds carefully. These steps help you get a smooth start.
How to Join Knitting in the Round
Lay your stitches flat on the needle with no twists. The working yarn should hang from the right-hand needle tip.
Bring the ends of your cast-on row together to make a circle. Insert the right needle into the first stitch on the left needle and knit it using the working yarn.
Pull the first few stitches a bit tighter to close any gap at the join. If there’s still a small space, you can sew it up later with the yarn tail.
Use circular needles for bigger projects and DPNs or the magic loop for smaller ones. Check again for twists before you keep going.
Marking the Start of Your Round
After joining, you need to mark where each round starts. Put a stitch marker on the right needle after the first stitch of the new round.
If you don’t have a marker, use a loop of contrasting yarn. It just needs to be easy to slide from one needle to the next.
You can also mark the end of your round if you’re using DPNs. This helps keep your rounds even and makes switching needles easier.
For projects with color changes, marking the start is extra helpful. Move the marker up as you go so it stays in place.
First Rounds: Tips for Success
Knit the first few rounds slowly and check your stitches often. Keep your tension even so you don’t get loose joins or wobbly edges.
If you’re knitting ribbing, like k2, p2, make sure the pattern lines up at the join. Misaligned stitches will show later.
Start with a few rows of stockinette or ribbing to make a stable edge before you switch to more complex patterns.
Here’s a quick checklist:
|
Step |
What to Check |
|
1 |
Stitches not twisted |
|
2 |
Join tight and smooth |
|
3 |
Marker placed correctly |
|
4 |
Even tension on first rounds |
Take your time on these first rounds. They shape the rest of your project, so it’s worth double-checking as you go.

Knitting Techniques and Stitch Patterns
When you knit in the round, you work the stitches a bit differently than flat knitting. You use the same knit and purl stitches, but the results look different since you’re always on the right side.
Knit Stitch in the Round
The knit stitch is the basic move for most circular knitting. If you knit every stitch in the round, you get stockinette stitch on the outside.
This happens because you never turn your work—the right side always faces you. Hold your circular or double-pointed needles so the working yarn comes from the back.
Insert the right needle into the first stitch on the left needle, wrap the yarn, and pull it through. Move the old stitch off the left needle and keep going.
If your stitches twist when you join, the fabric might spiral. Before you join, make sure all your cast-on stitches face the same direction. Even tension helps avoid loose gaps where rounds connect.
Purl Stitch and Garter Stitch
The purl stitch in the round makes the opposite texture of the knit stitch. To purl, bring the working yarn to the front, stick the right needle in from back to front, wrap the yarn, and pull it through.
If you purl every stitch in the round, the outside shows reverse stockinette. The smooth side ends up inside, and the bumpy side is on the outside.
For garter stitch in the round, alternate one round of knit stitches with one round of purl stitches. That way, both sides stay textured and the fabric won’t curl up on you.

Stockinette and Reverse Stockinette Stitch
Stockinette stitch in the round feels smooth and has a bit of stretch. You make it by knitting every stitch on every round.
The right side shows neat “V” shapes, while the inside has purl bumps. This fabric works well for hats, sleeves, and sweaters.
Reverse stockinette flips that look. Purl every stitch in the round, and you get the bumpy texture on the outside.
It’s a little softer and more textured. If your edges curl, try a few rounds of garter stitch or ribbing to help the fabric lay flat.

Methods for Knitting Small Circumferences
When you knit small tubes like socks, sleeves, or mittens, standard circular needles are usually too big. There are special tricks to knit small circles smoothly and keep your stitches even.
Each method changes how you hold your needles and yarn, but the goal is always neat, even stitches.
Magic Loop Method
The magic loop method uses one long circular needle—usually 32 inches or longer. You pull out a loop of the cable between stitches to split your work into two halves.
Cast on all your stitches onto the circular needle. Slide half the stitches to the cable and half to the needle tip, then pull the cable loop out between the halves.
Bring the yarn to the front, knit across one side, rotate your work, and knit the other side. This works well for socks, mittens, and sleeves.
It keeps stitches even and you only need one circular needle, so it’s pretty budget-friendly. At first, it might feel awkward, but once you get the hang of it, it’s really smooth.
Pros:
- Uses one circular needle
- Fewer joins and transitions
- Good for travel knitting
Cons:
- Cable must be flexible
- Loops can twist if your tension is off
Using Double-Pointed Needles (DPNs)
Double-pointed needles (DPNs) are the classic way to knit small tubes. You use four or five needles to make a triangle or square shape.
Split your stitches evenly, then use the extra needle to knit. Join in the round carefully so you don’t twist anything.
Each time you finish one needle, move to the next. DPNs give you really good control over your stitches and tension.
This method is great for socks, gloves, and hat tops. It looks a little scary at first, but after a few rounds, it feels normal.
Pros:
- No cable loops to handle
- Lots of pattern support
- Works for very small circles
Cons:
- More needle changes
- Stitches can slip off the ends
Two Circular Needle Technique
The two circular needle method uses two short circular needles instead of one long one. Split your stitches in half, keeping each set on its own needle.
Knit across one needle, then switch to the other. This setup cuts down on cable loops and makes it easier to see your stitches.
It’s handy if you already have short circulars and don’t want to buy a super long cable. You can even use different needle materials or sizes to tweak your tension.
This works for sleeves, cuffs, and small cowls. It’s a bit more stable than DPNs and has less looping than magic loop.
Just remember which needle is which so you don’t cross your cables by mistake.
Pros:
- Smooth transitions between sides
- Good for small-to-medium tubes
- Nice for people who like circulars
Cons:
- You need two matching circulars
- Takes a little longer to set up
Projects and Inspiration for Knitting in the Round
Knitting in the round lets you make seamless pieces that feel smooth and look neat. You can build tubes of fabric without sewing edges together, which is perfect for accessories and small garments that wrap or fit around the body.
Hats and Beanies
Hats are one of the easiest and most satisfying circular knitting projects. Cast on stitches to fit the head, then join in the round.
Use circular needles for most of the hat, and switch to double-pointed needles to shape the crown. Try ribbing to keep the edge snug, or play with colorwork for something eye-catching.
For warmth, go with wool or alpaca. For a lighter hat, cotton or bamboo is nice.
A simple pattern idea:
|
Step |
Description |
|
1 |
Cast on 80–100 stitches, depending on yarn weight and head size. |
|
2 |
Work 1x1 or 2x2 ribbing for 1–2 inches. |
|
3 |
Knit in stockinette until length is about 6 inches. |
|
4 |
Decrease every few rounds for shaping. |
|
5 |
Close the top and weave in ends. |
Adding a pom-pom or folded brim gives your hat a personal touch.
Infinity Scarves and Cowls
An infinity scarf or cowl is perfect for circular knitting. It forms a loop with no seams.
You can knit it long and twist it for a Möbius wrap or keep it short for a cozy neck warmer. Pick soft yarns like merino or acrylic blends that drape well.
Use bigger needles for a loose texture or smaller ones for something warmer. Try garter or seed stitch for texture, or play with stripes and gradient yarns for color changes.
Tip: Block your finished piece to even out stitches and improve drape. It really does help the scarf or cowl lay flat and feel better around your neck.
Mittens and Socks
Mittens and socks really shine with circular knitting because they need a smooth, tube-like shape. You can use double-pointed needles, two circulars, or magic loop—whatever feels best to you.
For mittens, start at the cuff, knit in the round, and shape the thumb with increases or a gusset. Wool keeps hands warm, and superwash blends are easier to wash.
Socks need to fit just right. Work from the cuff down or toe up, shaping the heel and toe as you go.
Use sock-weight yarn and smaller needles for a tight, tough fabric. Keep a stitch marker at the start of the round so you don’t lose track. That little habit can save a lot of headaches.

Frequently Asked Questions
What materials do I need to start knitting in the round?
You need circular needles or double-pointed needles (DPNs), depending on your project’s size. Pick a yarn that fits your needle size and grab a stitch marker to mark the start of your round.
Scissors and a tapestry needle help with finishing.
Can you explain the magic loop method for circular knitting?
The magic loop method lets you knit small circles with a long circular needle, usually 32 inches or more. You pull out a loop of cable between stitches to split your work in half.
This method takes the place of DPNs for things like sleeves or socks.
How do I join my knitting in the round without twisting?
After casting on, lay your stitches flat on the needle so they all face the same way. Before joining, check that the cast-on edge forms a smooth circle with no twists.
Put a stitch marker at the join to mark the start of each round.
What's the difference between circular needles and double-pointed needles?
Circular needles have two tips joined by a flexible cable and work well for bigger projects like hats or sweaters. Double-pointed needles come in sets of four or five and handle smaller circles, like socks or mittens.
Both let you knit without seams.
How do I switch to double-pointed needles from a circular needle?
When your stitches won’t stretch around the circular needle anymore, split them evenly among three or four DPNs. Knit across each needle in turn, keeping your yarn tight at the joins.
This keeps your stitches even as you finish up small sections.
What are some tips for avoiding ladders when knitting in the round?
Pull the first two stitches on each new needle tight to close any gaps. Try rotating your starting point every few rounds. This helps spread out the tension.
Some knitters like using one size smaller DPNs. You could also adjust your grip to keep your stitches even.
