here is a card holder. i laminated the front and back covers, and bought rings to bind it together and added some ribbon. dave thinks i went overboard with the ribbon, but i like it.
i used double sided 12x12 paper and folded it up and back to get a pocket on each side. it is Tres Jolie brand, a cardstock weight. here is a link for directions, in case you would like to make your own.
i have a pocket for each month, and a couple extra for Get Well, Sympathy, and Thanks.
