Including figuring out how to do them, it took me a little over an hour to make nine pairs. Now that I know how to do them, they can be completed in just a few minutes each. In retrospect, I think it might have been nice to cut a slit, like slicing a pie, and re-sew it so they would contour a little better, but the flat ones I made work just fine too.
One of the best parts about this project is that you can use thrift store flannel sheets to do it, for a cost of just a couple dollars with a ton of material left over. I used some new material I had purchased for the outer layers because I wanted pretty and my thrift store sheets were kind of bland, but I could have made all nine pairs with two standard pillowcases.
To make them, trace a regular CD and cut four layers of flannel. If you anticipate needing more protection, up to six layers seems to work fine. I have two pairs with six layers in them for those heavier days. Pin the layers together with right sides out. Using your sewing machine, finish the edges with a zigzag stitch. If you have a serger, it will make a more professional looking edge, but either way will create functional pads.
That’s all there is to it. Very simple, very fun and the best part – very practical.
