I'm so sorry to hear of your unfortunate experience. If there isn't a quilting buddy handy (I would gladly help you, but I'm in Ohio) would you be able to call your local quilt shop? At our local shop there is Tues. morning sewing, Sit and Sew and a UFO day. Certainly there would be a quilter there willing to give you a hand (pun intended).
Also if there is a quilt club or guild in your area I'm sure they would help a temporarily disabled quilter!
Hope your thumb heals quickly.
