This from ChristyRobbins: Take the couple’s invitation and cut into strips. Wrap around a pencil to coil up. Insert into a clear ornament. Give it as a wedding gift for them to hang on their tree every Christmas–simple, elegant, inexpensive, and will be treasured forever!
Christy advises this would also be cute for baby shower invites, or other special occasions.
