75 meter spool of no. 2 bare copper wire, 7 stranded
I've been wrapping glass with copper wire for fifteen years now, and I just figured out roughly how much copper I have used: A lot!
For wrapping, I use bare copper wire no. 2, 7 stranded, and I buy it in 75 meter spools. So the 7 strands means each spool has 525 meters of wire. I use two spools a year. Not counting my early years, where I did not use as much, I calculate that I have used at least 14,000 meters (28,228 feet). That's 9 miles of wire!
I still have a few of my early copper wire wrapped pieces around, and I can tell you that while maybe practice does not make perfect, it will take you in that direction. Below is a recent wrapping.
