My DH is very supportive--he's a writer and understands the passion needed to create and the work involved--and as far as my long arm quilting--he often will ask to see the back too if I've used threads that contrast with the backing so he can see the design better. I recently participated in a Guild challenge of mystery batiks and struggled with the creating--colors just didn't speak to me--and ended up with a pictorial quilt and we both liked the back better!
My BIL is of the "isn't quilted unless handquilted" camp but my Sis is gradually exposing him to greater variety.
