I made a few of these hotpads for a wedding gift to go with dishcloths, the towel hanger and towels to go with.
For the front you sew strips together in different angles till it is big enough. I used tons of scraps. The hardest part was letting go. There was one I wasnt sure I liked and by thw time it was a leaf I liked it a lot. In the middle there is two layers of batting and a layer of old jeans. If you would like the pattern for this size hotpad I can scan it in. We just made a leaf shape.
