I would suggest if the LQS is local, go on in and meet the owner or the employees. I use to quilt for a LQS and getting to know the employee will ease your fears. Just make sure you are signing up for a class you really want to take. My best friend took a class from the speaker that spoke at her guild and really didn't enjoy the class because she was a beginner and instructor didn't hand out any printouts which made it difficult for her to follow.
