The best way to keep warm is to keep your head covered. So, in this tutorial, I'll show you how to sew a beanie from scratch to keep you warm this winter.

Fleece keeps you warm and cozy on chilly days and nights whether you’re out and about or in your house. These make perfect gifts for a special someone or even for yourself.

Here, I’ll show you how to make your own beanie from fleece and as a bonus, from an old sweater. Let’s get started on how to sew a beanie!

Tools and materials:

Fleece beanie

  • Fleece fabric
  • Scissors
  • Sewing machine
  • Pins

Sweater beanie

  • Old sweater
  • Scissors
  • Sewing machine
  • Needle and thread
  • Wool
  • Cardboard

You can repurpose any fleece garment you already have or buy a small piece of fleece to make the beanie. Fleece is super easy to work with and doesn’t fray so you don’t need to hem it.

Fleece has one side that is stretchier than the other, so check the stretchiness before cutting and sewing. Your fleece may have a wrong side. If it does, make sure to pin and sew your pieces right sides together.

Cutting a square shape from the fleece fabric

1. Make the pattern

Check your fleece's stretchiness. Cut the fabric to measure 22 X 22 inches.

Folding the fleece fabric

Fold the piece so the right sides are together.

Pinning along the long open side

2. Sew the beanie

Pin along the long open side. Sew with a straight stitch, leaving about 2 inches unsewn just a bit above the center. 

Pulling the opposite corner together

Once it’s sewn, lay it flat. Lift up the right side and match the inner corner to meet the outer left corner.

Crossing the corners over

Then lift the lower left corner and match it to the upper right corner.

Pinning the bottom in place, ready to sew

Pin the flat bottom with the top and bottom layers. Sew with a straight stitch. Just before you reach the end, stop sewing.

How to sew a beanie

Tuck your hand in and open the folds from the inside and continue sewing all around, pulling out the folds.

Flipping the beanie right sides out

When you’re done sewing, find the unsewn hole and flip the beanie inside out.

Make your own beanie from scratch

Blind stitch the opening closed. Tuck the beanie fabric inside. You’re done!

DIY sweater beanie

Here’s a great way to repurpose an old sweater. Make sure it has nice ribbing at the bottom.

Cutting the sweater to make a beanie

1. Cut the pattern

Cut from the waist downward on one side.

Trimming the fabric to make a bell shape

Trim to a rounded at the top bell shape.

Folding and pinning the long side

2. Sew the beanie

Fold the sweater piece over, right sides together. Pin the open side seam.

Sew with a straight stitch, making sure to backstitch at the beginning and the end of the seam.

Flip the beanie “loop” or “tube” inside out.

Hand-sewing the fold in place

Determine the best length for the fold. Hand-sew the fold in place right along the seam. 

Hand-sewing a gathering stitch to pull

Hand-sew a gathering stitch at the top, pulling in the thread and knotting it tightly.

Making a DIY pompom for the beanie

3. Make the pompom

Use a piece of cardboard the size of a credit card. Begin wrapping the wool around it tightly until it is nice and fluffy.

How to make a pompom

Stick your fingers in to separate the wool from the cardboard and while holding it, remove the cardboard.

Tying a knot in the wool

Wrap the wool around the center, nice and tight, and tie a knot. You’ll have a sort of figure 8.

Cutting the loops to make a pompom

Cut the rounded ends straight across on both sides.

Trimming the pompom

Trim the pompom to your desired shape.

Attaching the pompom to the beanie

4. Attach the pompom

Push the sewing needle through the pompom and sew directly to the top of the hat. 

Adding a sleeve tab to cover the fold

Optional: If you want to cover the seam from the wrong side fold of the hat, you can use a sleeve tab from an old cotton shirt in a complementary or contrasting color.
