This is to help get rid of cramps, something I have a lot of trouble with. It consists of a crocheted cover and a cloth bag made out of the material of your choice. Try to avoid polyester, as I’m not sure how well it would do in the microwave. To use, pop the bag in the microwave to warm it up to a comforting temprature, then slide it back inside the cover so you don’t burn your poor belly!
Row one: With a size G hook, chain 41.
Rows two/three: Dc in second chain from hook, continue across the row. You should end up with 40 dcs. Ch1, turn.
Row four: bdc across the row, ch 1, turn.
Row five: repeat steps 2-4.
Go on for as long as you want the cover to be wide when folded. I did 154 rows, you can change this to meet your needs. Slip stitch the top and one side together. Fasten off. At the other end of the cover, make two 25 stitch chains on each flap to tie it shut with.
