I got the idea for heating pads here years ago and gave them away as gifts one Christmas (thanks guys!)
Now I'm thinking of making some pocket warmers for my friends in Canada who are freezing. I used rice in my last ones, but I know you can use other things as well.
Two questions:
1. What is the best filling for heating pads? Rice was a little prickly for me.
2. Can I use felt or something like that to make them? I want to make hearts and have them nice and soft. If not then can you recommend another soft fabric that would work? (I know they're supposed to be cotton but I don't know much about fabric)
Thanks in advance for any advice you can give!
