PaperPrincess, I feel your pain and disappointment. I agree with the suggestion that you wait until after the first of the year before shipping the quilt. Perhaps you could put it away for a few days, at least until your hands are less sore.
I don't know how large the quilt is, but I have invested in two long maple boards (7 foot = 84 inches). Sharon Schamber's technique for sandwiching the layers works for me. I've had success with spray basting sections or simply using the large "Z" tailor's basting stitch with a single strand of cotton floss. You might be able to accomplish the same thing using the pool noodle or cardboard tube from a roll of batting.
It's too bad that we don't live closer together, as I'd enjoy basting your quilting. There is something about the Z baste that puts me in a relaxed mood. My fingers seem to have less strain. Do you have a buddy who can help? Take care
