Every once in awhile, I burn out and just have to step away for awhile. That said, I usually have 3 projects going in different stages, one on the frame, one being pieced, and another being hand appliqued. None have a deadline. That way, I tend to work on one for a few minutes here and there whenever the mood strikes. Quilting is supposed to be my therapy so I try not to stress over it.
My husband laughs at me on "housework" day because I'll vacuum the rug and then go sew for a little bit, clean a toilet, and then sew for a bit. Next thing I know, the day is over and LOTs got done without thinking about it. Relax, let go of the stress.
