My girlfriend had a good amount of success selling her Megaman E-tank can koozies through her Etsy account and has started making 8-bit and 16-bit Perler bead sprites. You can choose whichever sprite you want from the 8 or 16-bit era for $8 (see the Megaman and Frog pic below for the size). Double-sized sprites (like Samus or the Metroid below) are $12. They’re all made to order, so if anyone is interested just drop me a line here or on the Cheap Boss Attack Facebook page.
Here are some examples.
And two more regular sized sprites.
And here is a double-sized Metroid.
