One nightmare I had in a class I was teaching...when you sign up for my class, I give you a list of supplies and how to prepare them, I suggest you have them cut out and ready to sew if you expect to complete the project in class. I had two friends come in and hadn't even bought their fabric so they shopped while I started the class and then they took an hour break for lunch and then complained at the end of the day because there was no way to finish this project in just one class!!!
