I think they said copper was easier for beginners to handle and maybe cause it was just a very small piece so it was ok. But given the workshop was free, it was really cool.
Seeing the Concorde up close and personal was really cool and I even went on board, can't wait to post that!!
I'm looking forward to seeing that. That makes sense about copper. I guess in that small of quantity, it isn't that big of a deal.
