I can see why you would hesitate to spend $200.00 on a class. I think you may find what you need from a less costly source. Join a guild , or other quilting type group. Or find a class, that has the specific components of what you think you need. I know I often teach skills one on one , for little to no money.
I would find out how many people are going to be in the class , somtimes too many people in a class does not allow for the one on one you might be needing.
