Nope - not getting mixed up at all. DMW asked about regular wire and when is best to use a simple loop as opposed to using a wrapped loop. DMW was referring to hard, half hard, & dead soft - round, half round, & square wire.
DMW also asked about nylon clear and color coated BEADING wire like Soft-Flex, Accu-Flex, and Beadalon. And all three manufacturers make a
100% Sterling Silver beading wire. As a matter of fact, I happen to have a
30' spool of 39 strand Accu-Flex 100% Sterling Silver beading wire and yes it was rather expensive - cost me somewhere around $30.00 to $40.00 bucks but it does make fantastic illusion necklaces like you said.
Accu-Flex and Beadalon make a 24k gold plated beading wire. Not sure about Solf-Flex but I'm guessing they do too. Although I use Accu-Flex exclusively, I still wont buy the 24k gold plated beading wire - because its plated. Yeah, I get that the nylon coating prevents the plating from rubbing off, but its still plated. If its not "genuine" (and I hate that word because its so overused) but if it aint real, then I don't use it. What really sucks is that there are more styles to choose from in pewter, plated, and base metal, but I cant use any of them because its not Sterling. I have to wait for someone to do it in sterling before I'll use. Somewhat limiting, I know, but if I could just find some metalsmithing classes around here, I'd make my own. That's kinda the next step.... making my own finding and components.
