After looking at work by artists I admire, I was baffled how they didn't get all the bumpy overspill of solder around their wonderful clean silver cut outs - until I remembered that you don't need solder if you are fusing two pieces of silver together. Definitely a 'duh' moment. Not quite as 'duh' as when it finally clicked that I could use my rolling mill to thin my metal to the gauge I needed instead of buying loads of different sheets, but pretty much up there!!
To say I'm a slow learner wouldn't be far off the mark, but I'm nothing if not persistent!
