This diecut bride and groom are attached with a small tab at the top. It gave me a flashback to those twirly pins we were always using at school. You know the ones that you pushed through and then split the leg-type bits? No? Well, anyway, it made me think you could use them to make your own save the date cards. Attached photos of the bride and groom maybe with a note in the back? Something like that anyway.
If I haven’t inspired you to get the scissors and craft paper out, then you can buy these from Paperbuzz.
