does anyone know of a good one, or blank ones you can buy and run though a printer? thanks

 this is one that I have found online

Why do not you make your own, I bought my cardstock here:

I liked the metallic look, it shines nice. I was not sure what to buy at first, so the person (costumer service rep.) was very helpful and sent me some samples on the mail for me to choose from before I placed my order.

and the thingy you tape in the back here:

I hope this can help you.
