How to make a hat from a sweater

Measuring for your sweater hat

This is the silly part, but hang with me.

First wrap the rib knit hem of the sweater around your head. Pull it down to a level where you want your sweater hat to sit.

Pinch the sides together so that it fits comfortably. Next mark this circumference with a pin.

After this, pinch the sweater up at the top of your head. Mark the top of your head with another pin.

How to make a hat from a sweater: cutting your sweater hat

First we need to draw our cutting lines. Draw a vertical line 1/4″ past your pin mark on the hem. After that, draw a horizontal line 1/4″ past the pin for the top of your head.

Cut up the sweater straight through both layers along both lines. That’s all we need to cut for now. We’ll give the hat some shaping in the coming steps.

Sewing the first seam

Fold the sweater knit right sides together. Sew with a narrow zigzag (0.5mm width, 2.5 length) down the vertical side. Be sure to backstitch at the start and end of this seam.

Lightly press the seam to one side. Stitch the seam allowance with a wider zigzag 5.0-6.0m right on the edge of the seam to finish the seam.

Now let’s shape up the crown of the hat.

Next, fold the fabric in half, then in half again so that the ribbing is at the bottom.

Move your pin so that it’s in the center of the folded fabric. Now make 2 marks 1/4″ away from the pin on either side.

Draw a curved line with your chalk 3″ from the bottom to one of your marks. Repeat for the other side. Make sure that the line tapers to nothing right at the top edges of the ribbing.

My sweater has fairly narrow ribbing. If yours has a wider ribbing, you can taper the curves to the top of the ribbing.

Flip the folded hat over and draw a second set of lines.

Sewing the crown

Unfold your hat. Now we need to sew up the darts we just cut.

Match the side seams together. Sew along 2 of the curves you just drew. Use a 1/4″ seam allowance and a narrow zigzag for the dart, and taper the dart to nothing at both ends.

Match the tops of the darts together. Now sew the second set of curves. Sew the other darts the same way to close up the crown.

Finish off the seam allowances with a wide zigzag. After you’ve finished the seam allowance, trim close to the zigzag stitching to finish the seam.

Embellish your sweater hat

This falls under the category of optional but awesome.

Cut several small circles from the leftovers you trimmed off. Overlap them, sewing on each with a small X with embroidery thread like I did in this refashioned sweater shrug tutorial.

Another idea is to stack a few circles together and make a small flower. Use a few hand stitches to anchor the flower on your hat. You could add a couple beads to finish it off like a proper flower.

You can also top off your sweater hat with a good old pom pom. Here’s how to make a faux fur pom pom.
