You mentioned that you recently finished the Bali Wedding star (sure looks challenging). I find that when I've completed a particularly challenging or long project I need to re-energize by either doing something else (like getting my nose into a few books, taking on a house cleaning or repair projects, etc) ; or explore a new technique. often I don't "finish" that exploration because I get focused on an unfinished project--but since I usually have many projects going at a time, I just add the "exploration" to the pile. check out one of Jean Wells books on innovative piecing. (I often just start piecing strings when I'm in a lull--just mindless sewing!)
