Rice Bags sewed but not stuffed

I learned in my natural child birth class that rice bags were the way to go to help with cramps and muscle aches. I made some bags today but I don't have rice for them. I'll go to the store on Monday and get some. I ended up with two long bags for my back or legs and 3 smaller bags for my hands or ankles. They stitched up really fast and were fun to make.
