There was grinding and wrapping in copper foiling and soldering and balancing and soldering and soldering and more soldering!
I really should have cleaned the solder off the glass and washed off the sharpie marker before taking the photos!
Seeing them together, I definitely need to add wire and beads to the orange/yellow/red one. I think it looks quite plain in comparison.
I could also do with improving my soldering. I'm considering buying a soldering iron so I can make these at home, to use up the scraps of glass I have and to practice, but if I can't cut the glass cleanly enough, I don't have access to a grinder... decisions, decisions!
