I use cling wrap on the end ( pull off a small piece) and twist it to a point then thread the RxW easily through. For 3mm RxW need around 2.5 coil and 2mm use 1.5.I wasn't impressed with it, went back to the rayon. For me the only thing it had going for it that it lasts a long time, cleans with dry burning. It can be a pain getting it threaded thru your coils. Of course there are those that swear by it, so you just have to try it yourself. What dia. coils do you use. I've got about half a foot of it you can try. It's the small dia. tho, maybe for a 1.5 -2.0mm coil, I forget which dia. coil I was using.
