Can you write on these signs for our son and soon to be daughter-in-law's wedding? Of course I can. Aren't they the cutest trays ever! Loved them. I thought their own handwriting would've been lovely too. On the other hand, I do love any excuse to do a quick project. It didn't take long, and the couple are just sweet hearts. Only problem was we were headed to the beach and we didn't get to go to the reception! I know that it was beautiful.
