I'm not sure what a potato bag is but I saw one or at least I think that was one. It had potatoes in it, so I assume it was for microwaving baked potatoes. Anyway, it looks just like the tortilla warmers that I have mad with exception of the flip lid to keep the tortillas warm. It is two quilted circles, mine were 12-15 inches , with one side cut about a 1/3rd of the way from the top and sewn onto the full circle or back circle, and the top part that had been cut off was sewn onto the top of the back circle, and overlapping the short front bottom portion, making sort of a lid. They were used to put flour tortillas in, in the microwave to warm up, and the tortillas were kept warm in the cover. Sorry not a real good description. Gerbie
