Check these out!
They're called Coaster Notz from modern-twist. You can doodle on these with a ballpoint pen and it wipes right off! These would be nice place cards for the rehearsal dinner!
They also have Vinotagz - a "modern twist" on wine glass markers! They come with a case that attaches to a wine bottle. These would make a great hostess gift!
I discovered this site thanks to Erin over at BrideDesign. She makes one-of-a-kind invitations and Invitastions (invitations you can eat)! Stop by her fabulous blog, Design is Everywhere.
