The fun thing about this project is that you can do it with a large group of people and end up with very different looking necklaces depending on the the paper used and the combination of wooden shapes.
You can buy packages of square or circle wooden discs at Hobby Lobby. I believe a package of the square were 3 bucks for 22 pieces to give you an idea of cost.
Next you will drill holes in them. Use a SMALL drill bit. The first one I tried was too big and broke the pieces of wood. For the square pieces you can either drill them in the corners for a diamond shape or on the flat side for the square. You will only drill one hole on the piece you will be using as your bottom pendant.
I preferred drilling the holes BEFORE I put paper on the front of them. I tried it both ways and there seemed to be more paper tearing when I drilled the whole afterwards.
Find a cute paper and use Mod Podge to stick it to the front. I like to cut a square just larger than the piece of wood, glue it on, and once it's dry, use sandpaper on the edges for a really clean transition. I would also suggest putting another coat of Mod Podge on the top of the paper after it's dry to seal it.
Press the paper with your finger around where you have drilled the hole and you will be able to see a little indention. Use a pin to break through the paper and rub it against the inside of the hole.
Connect your pieces with large jump rings. Needle nosed pliers come in really handy!
I tried to make the 2nd and 3rd pieces coordinate by putting the little green birds feet on the 3rd pendant.
I put it on a chain that I already had, but you can also use ribbon or twine or something if you want to avoid the cost of a chain.
**Side note, if I made this again, I would have painted the other side of the wood. The necklace lays pretty straight because of the weight, but if it were to flip around it would be nice to have a painted surface on the other side.
