Covering silver wire for use as a speaker cable


I have access to some bare very fine silver wire.
What can I cover it with so it doesnt short?
128x128ozzy
2mm cotton sleeves from RAM for proper litz braid, or various sized rolls of polyolefin HS tube from McMaster Carr if you just want to bundle 10 or so strands together inside one tube.
Ozzy, go to wirecare.com for shrink tubing in long lengths.I'd reccomend the 3:1 shrink ratio.They also have all kinds and colors of braiding,but no cloth type.Good luck and keep us informed on the project.
IIRC, silver is supposed to more conductive after it tarnishes. Is that urban legend or is the concern about the tarnishing just about appearance?
