A toboggan hat is a straightforward tube you knit in the round, then gather at the top

A toboggan (also called a beanie or watch cap) is one of the easiest hats to knit because it has almost no shaping. You cast on stitches in a circle, knit in stockinette stitch or ribbing for about 7 to 8 inches, then decrease all the stitches at once and pull the yarn tight to close the crown. The whole project takes 4 to 6 hours for most knitters and uses roughly 100 to 150 yards of yarn.

The hat sits flat against your head without a brim, so it works best in worsted-weight yarn (medium thickness) on US size 6 to 8 needles. You will need either circular needles or double-pointed needles to knit in the round. If you have never knit in the round before, this is a good first project because the stitch pattern stays the same from start to finish.

Key Takeaways

  • Cast on 80 to 100 stitches using the long-tail cast-on, then join to knit in the round without twisting.
  • Knit stockinette stitch (knit every round) or 1×1 ribbing for 7 to 8 inches, checking the fit by trying it on as you go.
  • Decrease by knitting two stitches together around the entire hat until you have 8 to 10 stitches left, then cut the yarn and pull it through the remaining stitches.
  • Weave in the yarn ends on the inside of the hat using a tapestry needle, then block the hat gently under a damp towel if the edges curl.
  • Common mistakes include casting on too many stitches (making the hat too loose), twisting the cast-on edge, and pulling the decrease yarn too tight and breaking it.

What yarn and needles you need

Use worsted-weight yarn in a solid color for your first toboggan. Variegated or striped yarn works too, but solid color makes it easier to see your stitches and spot mistakes. A single skein (usually 220 yards) is more than enough; most toboggans use 100 to 150 yards depending on how tall you want the hat.

For needles, choose either a 16-inch circular needle or a set of four double-pointed needles, both in US size 6, 7, or 8. The needle size depends on your yarn and how tight you knit. Check the yarn label for the recommended needle size, then go down one size if you knit loosely or up one size if you knit tightly. Circular needles are easier for beginners because you do not have to switch between four needles.

You will also need a tapestry needle (a blunt needle with a large eye) to weave in yarn ends, and stitch markers to help you track the beginning of each round. Stitch markers can be store-bought rings or straightforward loops of yarn.

Casting on and joining to knit in the round

Cast on 80 to 100 stitches using the long-tail cast-on method. The exact number depends on your gauge (how many stitches per inch you knit) and the head size you are making. For an average adult head, start with 88 stitches. If you are making a hat for a child, cast on 72 to 80 stitches instead.

After you cast on, lay the stitches flat on your needle and look at the cast-on edge. Make sure it is not twisted—the loops should all face the same direction and form a smooth line. This is the most common mistake at this stage. If the edge is twisted, pull out the stitches and cast on again.

Place a stitch marker on your needle to mark the beginning of the round. Knit the first stitch, then knit around in a circle until you reach the marker again. You have now completed your first round. The hat will start to look like a tube instead of a flat piece.

Knitting the body of the hat

Once you have joined the round, knit every stitch in every round for stockinette stitch, or knit one stitch and purl one stitch in every round for 1×1 ribbing. Ribbing is stretchier and fits snugger, so it is a good choice if you want the hat to stay on your head. Stockinette is smoother and lies flatter, so it is easier to see if you have made a mistake.

Knit for 7 to 8 inches before you start decreasing. You can measure this by holding a ruler against the hat as you work, or try the hat on every inch or so to check the length. The hat should cover your ears and reach just above your eyebrows when you try it on. If you are making a slouchy hat, knit for 9 to 10 inches instead.

As you knit, watch for twisted stitches (stitches that look like they are leaning the wrong way) or dropped stitches (stitches that have fallen off the needle). Twisted stitches usually happen when you move stitches from one needle to another. Dropped stitches are easier to fix if you catch them right away—use a crochet hook to pick them up and pull them back onto the needle.

Decreasing to close the crown

When the hat is 7 to 8 inches tall, start the decrease round. Knit two stitches together all the way around the hat. This cuts your stitch count in half. For example, if you cast on 88 stitches, you now have 44 stitches.

Knit one plain round (knit every stitch without decreasing). Then knit two stitches together again all the way around. You now have 22 stitches. Repeat this pattern—one decrease round, one plain round—until you have 8 to 10 stitches left on your needle. This usually takes 4 to 5 decrease rounds total.

On the final round, knit two stitches together until you have only 4 to 6 stitches left. Cut the yarn, leaving a 6-inch tail. Thread the tail through the tapestry needle and pull it through all the remaining stitches on the needle. Pull the yarn tight to close the crown, then pull the needle to the inside of the hat and weave the tail through several stitches to find it.

Finishing and blocking the hat

Weave in any loose yarn ends using the tapestry needle. Thread the needle through the yarn end, then weave it back and forth through the stitches on the inside of the hat for about 2 inches. This anchors the yarn so it does not unravel when you wash the hat. Trim any yarn that sticks out.

If the edges of your hat curl up (which happens with stockinette stitch), block the hat by laying it flat on a damp towel, shaping it gently, and letting it dry. This relaxes the yarn and makes the edges lie flat. Ribbed hats usually do not need blocking because the ribbing naturally lies flat.

Try the hat on and adjust the fit if needed. If it is too loose, you can knit it again with a smaller needle size. If it is too tight, use a larger needle size next time. Most toboggans stretch a little as you wear them, so a snug fit when you first finish is normal.

Common mistakes and how to fix them

The most common mistake is casting on too many stitches, which makes the hat too loose and baggy. If this happens, you can either knit it again with fewer cast-on stitches, or you can take out every other stitch before you start decreasing. To do this, knit one stitch, skip one stitch, and repeat all the way around. This cuts your stitch count in half without having to start over.

Twisting the cast-on edge is the second most common mistake. This happens when you join the round without checking that the cast-on edge is flat. The hat will have a spiral twist that you cannot fix without starting over. Always lay out your stitches and check the edge before you knit the first stitch.

Pulling the decrease yarn too tight and breaking it is frustrating but straightforward to avoid. When you pull the yarn through the final stitches to close the crown, pull gently and steadily. If the yarn breaks, thread it back through the needle and pull it through the stitches again. You can also tie the two ends together with a square knot if the break is near the end.

Frequently Asked Questions

What is the difference between a toboggan and a beanie?

A toboggan and a beanie are the same hat—the name just varies by region. Both are straightforward knit hats without a brim that sit flat on your head. Some people use "toboggan" for a longer, slouchy version and "beanie" for a shorter, fitted version, but the knitting method is identical.

Can I knit a toboggan on straight needles instead of circular needles?

You can, but it is more difficult. Straight needles require you to knit flat (back and forth) and then seam the hat closed at the end. This adds extra steps and creates a visible seam. Circular or double-pointed needles let you knit in the round, which is faster and creates a seamless hat.

How do I know if my gauge is correct?

Knit a small swatch (a 4-inch square) in stockinette stitch using your yarn and needles. Measure how many stitches fit in 1 inch. If your gauge matches the yarn label, your needle size is correct. If you have more stitches per inch, your stitches are too tight—use a larger needle. If you have fewer stitches per inch, your stitches are too loose—use a smaller needle.

What should I do if I drop a stitch in the middle of the hat?

Use a crochet hook to pick up the dropped stitch and pull it back onto the needle. Insert the hook through the dropped stitch from front to back, hook the working yarn, and pull it through. Repeat this for each row the stitch has dropped. If the stitch has dropped more than a few rows, it is usually faster to pull out the hat back to that point and reknit.

How do I make the hat bigger or smaller?

Cast on more stitches for a bigger hat or fewer stitches for a smaller hat. Start with 88 stitches for an average adult, 80 stitches for a smaller adult or older child, and 72 stitches for a young child. You can also change the needle size—a larger needle makes a looser, bigger hat, and a smaller needle makes a tighter, smaller hat.
