I choose flannel fabric for the printed side and terry cloth fabric for the white back. After doing some internet research, I found that these are the most absorbent fabrics and held up the best in the wash. Of course, this is based off of other bloggers experience. Only time will tell if they are correct!
If you own a sewing machine and have the know-how to sew a straight line, I highly recommend this project. It was quick, easy, and painless. And they turned out so cute!
