Bachelorette party keepsake or for a special Girls Night Out - have everyone sign their kiss. LOVE this idea of wall art. I would love to this for my bachlorette party by adding each girls signature before they kiss.
"To give to mom before the ceremony starts." -yeah, great idea if you want your mom to cry hysterically before you even walk down the aisle. Better idea: sneak it into her purse where she can easily see it, and let her find it on her own.
