I am making my mom a rag quilt and have enough flannel left to make her a rice/? warming bag. Pic of flannel below. My question to those that have made these and have experience using different fillings--what have you found to be the best filler as far as retaining heat, being insect/rodent free and the most comfortable? My mom gets very cold feet that she says seems as if she just can't warm through the cold months. She also has nerve sensitivity in her feet, covers seem too heavy. I want to make this for warming her feet--any suggestions are greatly appreciated.
Edit-I found a poem that was used with the warming bags a while ago and can't find it now-does anyone have the poem or know where I can find it?
