Hi - Here's a magazine file I made to hold 4.25x5.5 cards. You could probably fit 6-8 cards in there. The version that holds the 3x3 cards can be found under the templates on this site. I've made three coordinating cards so far also using the Raspberry Tart DSP. You can see all of them at my blogsite: www.PaperTreeLane.com
Hope you like it!
