I recently came upon a couple of old cassette boxes in my house. I then came upon a nifty little idea to turn them into a stand for small desk items, like post-it notes, business cards, or tiny photographs.
You will need: one cassette box and one piece of paper (any kind will do) cut to 4'' by 3.5''
Open your cassette box as far as it can go, and put your paper inside. (This step is fairly self explanatory)
In case you happen to make a bajillion of them, they are pretty compact for storage.
