Just a note of caution ladies --- if you are putting these bowls into the microwave, be sure you are using the batting SPECIFICALLY made for use in the microwave. 100% cotton batting has a polyester "scrim" that holds it all together. It is flammable and I have heard many horror stories of microwaves on fire because of it! Joann's sells packages of it in the batting area ---- I believe it was first made for the potato bakers.
