I am an artist and would love to remember my wedding day with a beautiful piece of art. Instead of a guestbook each guest will create a mini 3x3 inch canvas that will go together in a collaborative piece of art. Would you be intimidated and pass this over at a wedding you attended? Many of my guests are also artists, but there are a bunch that are not. Also, should I control the color palette, or let guests go wild? Finally, should I have them draw hearts or leave it open to whatever?
