How to Make a Pair of Armwarmers – Step by Step Sewing Tutorial

This is a super quick and easy tutorial – perfect for beginners!


You’ll need:

  • A t-shirt with a sweet pattern or about 1/2 yard of fabric
  • Sharp scissors
  • Sewing machine or needle and thread

Step 1
Measure around the top of your arm (where you want the top of the armwarmer to reach) and around your wrist.

Determine how long you want your armwarmers to be and add a few inches for hemming. If you don’t mind raw edges, or you’d prefer to finish the edges of the armwarmers with lace or trim, you can skip hemming all together.

Step 2
Now you’re going to cut some trapezoid shaped pieces out of your t-shirt or fabric. The widest end should be half of your upper arm measurement, and the skinnier end should be half of your wrist measurement.

Cut through both the back and front of the t-shirt so you wind up with 4 trapezoids. If you’re using fabric instead of a t-shirt, fold it in half before you cut so you wind up with 4 pieces.

Step 3

Lay each set of trapezoids so that the outside or “right” side of the pieces are facing each other. Sew up the side seams and hem the top and bottom if you want. Turn them right-side-out and ta-da!

You can add lace, buttons, whatever you want.
