The guild member who made my potato bag did everything just right and it went up in flames on the first use.
I like casserole carriers. I'm sure the round one could be done in that time frame. If you are interested, I can look up the tutorial that I printed out for my church group. If they want to work together in small groups - one cutter, one person at the machine, one presser, etc, it would go quickly. Three people can make three faster than one can make one.
