Pocket Letters with a twist!

A pocket letter was just canceled and I decided to do one. You will use your baseball card holders and fill them with whatever you choose. This is not profile based but you must fill one baseball card holder and send a empty baseball card holder for your swap partner for the next swap.
Your going to love pocket letters! When filled they are folded and put in a business envelope but do check postage! This is a regional USA swap! Note or letter required in your pocket letter!
