I don't think I've ever gotten burned out, but I sew when I want and when I don't feel like it I don't. I mostly do quilts "just because" (unless it's for a baby), so I don't have any deadlines that get me frustrated or crazed. I say take a break and don't worry about it. Do something else you enjoy, or just do nothing for awhile! It'll be there when you're ready. :D :D
