I keep a list on my computer of all the projects I have 'going' and re-organize it about once a month. It has a couple of quilts that I bought material for years ago and have done nothing else to and several that I need to complete (hand-quilting, bindings, labels) for our upcoming show (Sept) as well as some that are in various stages of sandwiched, special patterns I am gathering material for, charity lap and infant quilts, gifts I would like to make, lotto blocks I have won and need an inspiration to put together, a themed quilt for a show next year that I am collecting material for, twelve totes for a raffle (the quilt is finished now). I sort of look at when each needs to be done and rearrange priorities that way. I usually have 4 or 5 things I am actively working on and the rest are 'cogitating'. I print my list and tape it inside my quilt sketch notebook.
