This picture shows 117 $1 stamps in 2 boxes. Boxes were created from a recycled large PO mailing box Each $1 stamp is stored in a cello bag sleeve cut from a Baseball Card page protector. (If you have a fuse tool you could do this without losing the center column of pockets) They are filed by categories coordinating with my ScrapRack categories - Alpha-Numeric/ Borders/Shapes/ Sentiments, Themes, Calendar Year.
They are also cataloged in a 6x9 binder so I can flip through the binder for inspiration then go right to the category I need and easily find the stamp.
