Thanks heaps, I started with a flat sheet of brass and cut the pattern in it first, then bent it into a tube. I use a jeweller's saw to cut out the design. I must say it's one of the most handy tools ever, even if you don't make jewellery. Kinda like a coping saw but with a ridiculously fine blade
Definitely, I use mine for all kinds of non jewellery stuff as well. It is not an expensive tool, maybe $15 on ebay. Just get good blades, makes a big difference. I have a little tutorial on another website here [link] Your work would look even more amazing with metalwork added.........And it's already ridiculously awesome.
