Hello Woodkhcr, sorry to hear of your bad experience but it happens quite often - I joined sewing class at LQS and spent two weeks teaching others how to use their computers to transfer designs to disk, cards etc and how to organize their files because the teacher was not very computer literate!! In first class I stitched one bird design which was in my new machine, next class we were lectured about feet and needles available in the store and I didn't even turn my machine on. Gave up on those classes, of course - we pay A$65 per proper class on average in Oz.
You learned not to be taken in so easily in the future, so hold your head up and rely on the people here to guide you
