My progress....
Got the annealed copper sheet, also messed up one of them, so I left it for 4 mins on the gas stove of my cooker, and managed to get it glowing bright red
so now its soft enough for me to start again.
The problem is bending them all the same. they bend easly, but theres no way atm to get them the same. Im thinking of maybe making a mold in clay of how I want it. Then to anneal tehse the most I can, then hitting them into the mold, how well that would workI dont know, and I doubt clay would be much good either, unless I could get these to anneal more.
