I always have some anxiety before I quilt on my sit down mid-arm too. I think it is just the perfectionist in me. I want to do my best and wonder if the design will enhance the quilt or detract from it. Once I start quilting, I relax and begin to enjoy the process and the transformation. I asked my longarmer friend who has been doing it for over 10 yrs. and she still has some trepidation too, so I think it is an individual thing, based on a lot of things. I've seen your quilts and you do a wonderful job.
