I think we all have dry spells now and again. I would suggest joining a Quilt Guild, taking a class or even going to a quilt show, all of which I've done in the past to get recharged. Start small, and I doubt that even the best machine quilter started out with a masterpiece, learning to machine quilt takes time and practice, but don't get discouraged. Or, you could try a completely different craft, which might inspire you in a different direction altogether, or get you back to quilting.
