I put warm and natural left over batting in them but you could use toweling or anything that is absorbant.
Also liked the idea earlier of making them as potholders and using insulbrite. Lots of ways of doing this pattern, easy, fast, and nice gifts. Also if you make them from scraps of Homespun material you don't even have to turn them inside out. :wink:
Thank you all for nice comments. :D
