You'll need a cardboard cozy from a local coffee shop to use as a template, a small piece of fabric, lining fabric, batting, 4 inches of thin elastic and a button.

Trace around your template onto your feature fabric and lining fabric. Cut out 1/4 inch bigger than the template for seam allowance. Lay one of these on top of the batting and cut around it.

Place the batting on the bottom, then the lining fabric, wrong side facing the batting, then the feature fabric on top, right side down. Remember to place your piece of elastic at the straight small end of your cozy, between the lining and the feature fabric. Fold it and place the raw ends on the raw edge of the fabrics, as shown in this picture.


Pin all of the layers in place and stitch around the edge, with a 1/4 inch seam allowance. Leave 2 inches on one of the long sides, so that you can turn it all right side out. Clip the curves for easy turning.

Turn it right side out and press.

Top stitch 1/8 in from the edge. Audition the placement of your button, based on how long your elastic is. If I did this again I'd probably make my elastic a bit shorter, and place the button closer to the closure of the cozy wrap, just because I think it would look better. Sew your button in place with a double strand of thread for durability.

Try the cozy on your cup and admire your work! Please let me know if any points are unclear.
