Shirley, aka Okieladybug, shared her cut. file to make little boxes to hold individual cartridges. They fit perfectly into a brand of storage containers called Really Useful Box she found at Staples. Since I don't have a Gypsy, I used her file that cuts three at a time to make mine.
She picked up one of the storage boxes for me since there's no Staples in my hometown. I'll pick it up when I go down this Thursday for stamp club. Meanwhile, I found an empty Rubbermaid box in the garage and stacked them in it.
Prior to her finding the new storage boxes, I had all mine in some Plano tackleboxes that are made to hold spinner baits. They work great but I had several boxes full and each time I needed a cartridge, I'd have to look through them to get it. With the new box, all of mine will fit into one, making it easier to store them and locate the one I want. I don't remember how many Shirley said will fit into the Really Useful Box; since I only own fifty-nine cartridges, I'm sure that all mine will fit into a single box though!
The only cartridge not in a little box is Pop Up Neighborhood that I received from my Circle membership. It's not one that I plan to keep but just haven't decided yet how to get rid of it! It's just sitting here in its original packaging ready to ship off to someone who can find a use for it!
