I bought this Snapware Smart Store container at Joann's (I think it's called the 14x6).
I made divider tabs with manilla folders and cut the clear tabs out of a transparency. I use one of the tabs on From My Kitchen. Make sure that when you attach the tabs to the divider you use a STRONG adhesive or re-inforce it with tape because of how stiff the transparency is. Then I just made the inserts on my computer - the fonts carts are in pink and the shape cards are in blue. (I know slightly compulsive - lol!
Next, I bought the little favor bags from the wedding section and each cartridge goes in one that I tied to the spiral binding of the handbook. I store the overlay inside the font cover of the handbook. The top of the photo shows the way it gets stored in the container and the bottom shows where the overlay is kept.
Here is a picture of my "craft area" as I don't have space for a whole craft room - ::: sigh ::: ah, to dream... You can see the container under my pink and brown scrap tote. Sometime soon, I will give you a "tour" of my little craft area. :)
