I'm looking for a pattern and instructions for a bag that is filled with Styrofoam pellets like those used in bean bag chairs. The bag is used to keep hot foods hot and cold foods cold. I would appreciate any help. Thanks.
I have used rice and cherry pits in the bags that you are describing. This address tells you all about the uses of cherry pits: http://www.cherrypitstore.com/ Styrofoam pellets may actually melt if the heat is high enough. Your fabric choices for the bag itself should also be 100% cotton to withstand high heat (i.e. microwave).
