DD had me do signature blocks for her wedding. I used a rail fence variation, ironed freezer paper (seam allowance smaller)) to the back. Some guest still wrote to the very edge, even though it was explained to only write where the paper is. They are not quilters, they do not regularly write on fabric (holding pen on the fabric will cause it to bleed?).
So now my DD has a wedding signature quilt with the end of a name missing, or part of a word is down in the seam or extra dark spots where the pen 'rested'. Oh well, it is what it is.
