I have taught quilting classes. I usually have a kit to make the block I am teaching. The class is to learn a technique not finish a huge quilt. I cut the fabric in strips so they can subcut it to the necessary size. Make sure you charge for your time. It takes a long time to cut fabric. Make sure students pre-pay the teacher fee and kit fee. I have found people forget to come to class and don’t want to pay for the class or fees. You have already done most of the work before the class even starts. Always provide a detailed list of supplies they need to bring to class. I also give them the amount of each fabric they will need to take the block and make a quilt.
