I can get 6 bags from one yard of potato fabric, then use 1 yard of cotton batting, and 1 yard of muslin.
One yard cut 12" by WOF, then cut that in half, you will have two tops, as far as charging goes, I charge $12.00 a bag, you are still making money on them. I cut the same in for Tortilla warmers. But sew the top up to with in a inch, so you can get the tortilla in the bag easier. I have made many of them, great gifts.
