I use cloissonne wire from Rio Grande. Learned about it from Mark Silver, it is what he uses. It is available in 36 and 38 ga, is .999 pure and comes in dead soft or half hard. Half hard is easier to work with. A 50 foot spool is less than $20.00. If I need something thicker Rio Grande has silver strips in any size you can imagine, or but sheets like others here suggest. Silver cuts and works very easily. German silver is only good for shimming up a wobbly drill press in your shop.
