sleeving AudioNote tonearm wiring

Hello,
Recently tried newly purchased AudioNote silver tonearm wires on a couple of my arms (Ortofon RS-212D and Sumiko MDC800), I should say I was impressed in a positive way. Now I need to finish the project, I am going to install it into Sumiko. What I am looking for is some advise. I am planning to put either cotton or silk sleeve outside, if somebody can share a good distributor for cotton/silk sleeving material. Also, would be nice to read up / hear any thoughts on the procedure. In particular would love to hear opinion whether or not I should apply any extra insulation before it is put into the sleeve. The wire itself is already insulated of course it is not a bare wire but I was not sure.
Thank you,
Anatoliy
