my ideal quilting classmate -
Shows up on time
Has supplies and tools needed and ready - this assumes a list was available
If sewing machine is required and class is not for how to use your machine - at least know the basics of how to run it - have an extra needle for it, too.
Shuts up while the instructor is instructing
Is friendly to everyone
If class is for Technique A - tries it without fussing - it might be better than Technique B that he/she knows how to do
Asks relevant questions
I don' t always get it the first time - so please - let me be able to hear and see as much of the instruction as possible that I came for
Taking a class is a fairly big deal for me - I want to get my time and money' s worth out of it.
