I found some fallen tree banches about 5 inches round (however you can use any size you like!), and let the wood dry for several weeks beforehand.
Then I used a jigsaw to cut the pieces about 2 inches thick. Following that I just cut a slit in each and made my name cards on the computer! Worked out really nice and was a great fall idea!
If you're not too handy and would rather buy some- go to etsy.com where they have many different choices!

If you grow pumpkins, you can also use them in a smaller wedding!
You can also use your wood for table numbers!
