Originally, I was going to use towelling. I felt wipe clean material was cold on a baby and I wanted something that would be comfortable and washable. When I was telling a friend what I was making, she went and brought me some material to use. She's from Sweden, and it's readily available there. They buy it by the metre to make waterproof sheets and for bibs. It has a towelling front, and a rubbery back. The bonus is, it's washable up to sixty degrees. It was perfect for this little changing mat.
