This one is a few years old, but I found the photos on here and enjoyed reminiscing. It's a project I'm pretty proud of, because I put in a lot of work and it came out so well. One time, I made this really cool stained glass portrait! I started with this photo of my Popo:

I printed it and traced the shapes I wanted to use on his face, and cut them out of cardstock. I numbered the lines on the cardstock so I could figure out how they went back together:

Then I traced the pieces of cardstock on my glass and used them as guides to cut and grind the glass shapes.

Then I wrapped each glass edge with copper tape to make the solder stick, and soldered it all together! The photo of the final portrait is a bit blurry, but I was pretty pleased with it.
