I personally love Barry's black sleeve It's a shame that there is no stretch to it but it is so tightly woven that it doesn't matter anyway. Could do with a slightly smaller diameter so that it hugs the wire better though.
Today was Court so I haven't started it yet. I'll be starting in soon as the "workbench" is cleared off and wiped down and first thing tomorrow. I don't work on messy surfaces. Though I do mess them up when I get at it.
