You might remember emptying out eggs as a kid, ready to paint and decorate. Well here's an egg-ceptionally cute idea (sorry had to be done) from the clever folks at Present&Correct.
Hollow out your egg as usual with a pin, paint and slip a note inside. To turn them into escort cards simply write your guests name on the outside and they can crack it open to find their seat! Cute! You might even say a cracking idea (sorry) You can find the picture tutorial on Poppytalk.
