What a NEAT idea! LOVE it!!!! Nancy, you just need to register with Pinterest, then when you see a kit you like in the store, just click on the little "P" (Pinterest) icon. When you click on that "P," you will be taken, like magic, to YOUR Pinterest account. Just sign in, if you are not already, and a window will pop up, letting you choose which board of your own you want to pin it to. Here is quick You Tube video that you might find helpful.
