Take a break and breathe and do something else for a bit- If you're like me- you're brain will still be chewing on quilting projects while your hands are engaged in something else. For me, it's often sitting at my keyboard and playing music. Oddly, sometimes, even doing some housework helps. This is just part of the the ebb and flow of the creative process - we must allow ourselves time to refresh our creative wellspring once in awhile - your energy for quilting and desire will return. Have faith.
