My March Bride was the first to do this (we'll call her a trend setter). I loved this unique idea of your guest making thumb prints instead of the usual guest book. You can buy ink pads to match your wedding colors and have a great canvas to hang in your home after the wedding.
Get a great frame, an a sturdy table (I do NOT recommend an easel) and you're all set!!
|note: this was from a birthday party, not a wedding.|
