This is a piece I did for my valentine <3. Entirely made of old watch parts, it was mostly soldered together with a small-tipped iron. The piece was inspired by the lovely and intricate designs of Justin Gershenson-Gates, who is one of only a handful of wonderful micro-scale artists.
If you'd like a full instructable, please let me know. I plan on doing some more small scale artwork like this, and would love to share my method.
