Hey all-

I am learning to sew on a sewing machine and need a project idea. I thought about making a removable sleeve or cover for heat packs for emergency use when transporting reptiles.

Could I go with something that is a cotton blend, or should it be heavier like flannel or fleece?

Also what do you guys think about those handmade heating pads. All they really are is rice in a bag that is heated in the microwave. They're supposed to retain their heat for awhile. Do you think they would work when transporting a reptile to and fro? I don't mean shipping, just to the vet or to a show.
