One of my first Pop-Up card designs. When I first started archiving patterns to a CD, I labeled the disc Pop-Up card. Almost impossible to find in a sea of a couple hundred.
Now I give every design a number so I can find it numerically or by alpha. I don't know why I didn't have a better system to begin with. Now that I think about it a bit- it makes sense as some art projects I am happy to make one or 2 but then I want to design something else and I do not keep patterns for everything.
