May be you have an old towel that you don't use it anymore but you don't want to get rid off it, or may be it is not so old but your dog tore a part of it? OK you can use it to make a great pair of warm slippers.
Step 1: Measure You Foot Size
For this step I used a thong to measure the size I wanted for my slippers.
I used a foam sheet because I can use pins to cut the towel then.
