The way I do the skirts is usually with 2 silicone and 1/2 tab of living rubber. I wrap thread around the jig throat, put the rubber on, wrap a couple of wraps, place the first silicone skirt where I want it, wrap a little more thread, place the second silicone tab and wrap a little more thread.
That gives me exact control over where everything is going to be. Then I wrap the wire, cut off the ends and finally, cut off the thread.
My process sounds more cumbersome than it actually is.
