I got my wood cake topper from Crafty Eddy. You can email him and he will send you a gallery of his work. Then you just choose the size (I chose about 5 inches) and he will make it and send it to you.
Here is his email:
craftyeddy@gmail.com
Then I spray painted it pink and hot glued different size/color perals all over the front. It was pretty simple actually and I love how it turned out. The pack of pearls I got from Michaels and they were on clearance, but I am sure they have something similar. (otherwise search online).
If you have any other questions let me know!
