One of the ways I help myself fall asleep is to complete sewing projects in my head or create new ones as I ease off into the realm of sleep. I have so many specialty fabrics in my stash that I am vacillating between Christmas stockings, tote/grocery bags, placemats, and other small kitchen accessories. I have a couple patterns for tops I want to cut out for myself. I also have fabric I'd like to make pants with. For now, though, time is an issue, so I'll work on designing those items as I drowse and nod in bed.
Though it's not specifically project oriented, I am finding that sewing still helps me keep myself centered and brings me back to a place of my own when there is chaos all around me. I can focus and simply be. That, again, is the zen of sewing, and I hope it rings true for you as well. Sewing is our friend. Our very good friend.
