Leftover wedding invites?

Make a collage of them and put in your album? Or make a collage and make it a unique cover?

Make Christmas decorations.

You can cut them in strips and place them in clear glass or plastic Christmas ornaments. Google pics. You can add silk flowers in your colors, pearls, plastic rings etc.

Oooo following for some of these cute ideas in case we end up having extras although I’m actually really worried we didn’t order enough save the dates.

Ok soooo not sure if you wanted to incorporate them into a project like PPs have suggested, but here is what I am doing with my leftovers: sending to celebrities 😂
if you send an invite to Mickey and Minnie at Disney World and/or Disneyland, they will send you back a signed picture and a “just married” button! Address it to Cinderella and Prince Charming and they supposedly send you a certificate. Sending to the White House gets a signed letter (really I think they just stamp it with heir signatures, and I won’t be doing this but just another option). People also send to like P.O. boxes for fan mail to celebrities and some have gotten responses! Google it, there’s a whole bunch of people you can send to. Instead of letting my invites just sit around unused and probably get thrown away eventually, I’m at least sending one to Disney!!
