I made a Soup Bowl Hot Pad using this tutorial.
All you need are two 10 inch squares of fabric
Two 10 inch squares of batting, toweling or flannel (padding to go between the layers of outside fabric)
It's sewn with a straight stitch, so if you can sew in a straight line you can do this. The pad itself is completely reversible and it is washable.
I am going to sew some more of these now I have made my first one.
