Sometimes I'll put a "work in progress" away and move on to something else but I always go back and finish it. If I'm not inspired, it's a chore to work on a particular top. I always get reinspired after a break. Oh, I have the "Bali Wedding Star" pattern "box" too! I'm excited to choose fabric for it and begin! I think this quilt will take a long time to complete and I think it will be on that I'll have to put away, work on something else and then take it out again. I get bored looking at and working on the same thing for an extended time - maybe it's ADD!!
Anyway, don't worry about putting something away - just don't start several!! Good luck!
