I thought I would share with you how I store non assembled cards. Once I have decided on a card if making multiples I cut all the pieces together. Place them in a somewhat order in a pencil box. I bought several pencil boxes in the fall when on sale for 15 cents.... This process has worked really well when preparing for swaps or mass production. I also place a sketch or completed card in the pencil box so I don't forget what I had in mind.
