What better way to say Thank You to your guests than with a "Thank You" sign or banner? When I married almost 8 years ago, I created hand-painted thank you signs that myself and hubby held. Our photographer took a photo and we used that image with our thank you notes we sent to all our guests. I attached it to the card with photo corners so the photo could be removed by the guest. They were a huge hit. Below is just some of the many "Thank You" signs available on etsy.

Along with the many "Thank You" signs available on etsy.com, there's also "Just Married" and "Mr"/"Mrs" signs too which make for some really cute photo props.
