I have two boxes like that. One for orphan blocks I have collected and one for designs I made with my embroidery machine.
If I ever get to it the embroidery one should be rather interesting. I have designs ranging from flowers to Native American patterns, redwork butterflies to motorcycles and guns.
Alot of my orphan blocks are used to make little barbie quilts from the grand daughters. After all even Barbie needs a quilt to go with all her other stuff...lol
