Thankfully the FMQ class I took was very small (just me
as the others didn't show up...which was rude).
The teacher got to sit down and work on such a variety of things. She kept saying, well, since you are comfortable doing "this" or "that" let's try doing "this" now. She showed me things that wouldn't have been covered in the normal class and I was really grateful she didn't cancel the class since it was just for me.
I took the machine I planned to use even if it meant lugging a heavy machine from the car....I didn't think it would work for me to practice on one and then try to use another one.
Good tips to remember. Also remember, the teacher is trying to share her knowledge and time -- have some common courtesy and respect for that too. Most teachers aren't pros and doing it out of the goodness of their hearts and the love of quilting.
