Thank you all so much for your input. The classes won't start until the end of October or perhaps November. So I have time to get more information about the level of ability from the QS owner. And, I'll take that in consideration as I plan what the classes will include.
I do think sashing and mitered corners are important, too. So, maybe it should definitely be a quilt and not just wall hangings.
I always feel comfortable asking you all for help. And, you always come through.
