I like the idea of taking the seam allowance around something like freezer paper or cardboard...because even though I had seam allowance marked many people wrote into that area. It's probably safer if they just can't do that! I also had people sign on the wrong side of beige tone on tone fabrics even though I had someone at the table to help folks with questions etc. Yikes!
Another sentimental idea...I made my DDIL's wedding dress and at the last minute wrote their names and wedding date on the hem of the dress lining with blue pigma pen much like you might write inside a wedding ring. She loved it! I got the idea from that being done on Christening dresses handed down in families & worn by multiple babies. (Baby name & Birthdate embroidered on)
Every happiness for you and your groom!!!
