I found these little glittered styrofoam pumpkins in the dollar bins at Michael's a couple of weekends ago. They came 2 to a pack and were $1.50, or 75¢ each:
To make them into place card holders, I took a razor blade and cut a small slice across the top of the pumpkin:
I didn't cut very deep, just deep enough for the place card to slide into the stem and sit on top of the pumpkin's ridges.
Then I repeated the same cutting process for each place card holder I needed:
Inserted the place cards I designed to match my "I'm thankful for..." dry erase board:
Instant place setting personalization!
Told you it was easy! :)
