Having people sign various blocks of a complete quilt would be difficult. What if somebody played a prank?? What if the quilt was a queen size top?? Can you see the difficulty with moving the sections around then be sure it won't move while someone signed it?? I found that I made the seam allowance larger and then placed 1/4" quilting masking tape around just inside the seam allowance. There is always someone who makes a mistake while signing.
