I have no idea on the duct tape thing, but is there a church nearby that would let you go there and use their tables to lay out the quilt and 'do your thing' I am not sure where you live, but if there is a small school near you maybe they would let you use the cafeteria tables some afternoon after lunch has been served. Just some possibilities. I am sure others will come up with some good ideas for you as well, and I will be anxious to hear about the duct tape also. Would painters tape work?
