Here is my new cartridge storage. It hangs on the wall right beside my bugs, so swapping cartridges is a breeze. The clear pockets allow me to see the cartridge names, and prevents me from having to move labels as I aquire more cartridges. It is a calander pocket chart and can be found at the office supply store Staples http://www.staples.com/office/supplies/p1_Pacon-Monthly-Calendar-Pocket-Chart_103761_Business_Supplies_10051_SEARCH. Six of the rows have seven pockets, and the top row is one long pocket. It will hold 49 cartridges and I love this new solution for storage!!!
