I remove my clear stamps from the sheets they come on and put them in cd cases. I take the sheet with the images and tape them on paper, put them on page protectors, and sort them in a binder by type. I can flip through the binder when I'm looking for ideas. My Studio G and other small clear stamps are in baseball card holders in another binder. My rubber stamps are in Sterilite drawers arranged by type. I don't have very many so I can just open the drawers to see what I have.
I keep a small notebook in my purse with my list of Stickles colors, Cuttlebug folders, etc. so I don't buy duplicates.
I'm thinking about stamping all of the images on paper and adding them to my original binder just to make it easier.
