Here's something creative and fun (not to mention super easy!) for your next dinner party: create a place card holder by simply putting a LEGO minifig on a block!
All you need to do is place a Lego person on a Lego block so it will stay up. The hands of the Lego will keep the card in place, no need for glue. May the crafty force be with you.
Now why didn't I think of this before! ... Link - Thanks Amy Cottrell!
