these are bags made out of cotton for cooking potatoes in the microwave. everything has to be 100% cotton - material, batting, thread. you can also use it for corn or dinner rolls[/quote]
Can you tell me what is the advantage of using a potato bag in the microwave? Do they cook faster? Never heard of such a bag. Why not ask your friend what she paid for the one she has and then decide if you can make one at that price.
