You pick out your favorite MBS project(s) and pin them on Pinterest.
Make sure to include the following tags:
Four winners are going to be picked to win a kit to complete the project that they had pinned. Which just rocks.
There's another two chances to win by linking up a blogpost here at the Love It, Pin It, Win It Contest page.
That page also has a more detailed description of the rules.
I've already seen a couple of pins of my Moda Bake Shop project which just absolutely, completely makes my day. There are some amazing projects at MBS and I still have trouble believing that you can find something of mine on that site.
What are you waiting for? Go forth and pin!
