I have been working on doing this same thing. Here is a link to the album in my gallery with my recipe cards.

I am also scrapping the back side to include a picture of the completed dish. I am doing mine 5 1/2 x 7 1/2. I had originally planned on getting the Basic Grey lunch pails to put them in and sort by category but recently found a nice big box at Michaels that will work great to hold them all. I am about to make dividers to put in it also.
And, if any of you are interested, there is a recipe card challenge going on in the challenge forum. It is not for prizes more just to motivate each other. Come check us out.
