I use 505 frequently on quilts on my longarm if I have a floppy side border or to hold the bottom border down to the batting after I unpin it from the leader. I remember reading somewhere that the National Quilt Museum uses 505 when repairing their antique quilts because after 6 months (with no washing) it is gone completely, leaving no residue. I would think that if you used the 505 and washed the quilt after it was bound, you would not endanger anyone with the chemicals.
