Hey, I'm not part of the anti-spit brigade. I do find that using thread heaven on the full length of my thread seems to help with the kinky types. For whatever reason, I notice a difference in particular with overdyes, and silks, rayon - which I usually dampen instead. And metallics. I'm sure as heck not licking an entire stitching length - that's a picture, isn't it!
That is pretty darn long. Maybe your needle or hole is big enough that it just works on the kit. Glad it's working for you.
Interesting. I stitch 2-handed most of the time as well. But, I'm using the underneath hand to assist when doing the 2-hole thing. Usually, I don't do the up with the down simultaneously when using any kind of bulky, sticky thread. But, I'm guessing we do some similar kind of technique. However, I don't do such long lengths of things which I fear will either de-fuzz (e.g. Whisper, arctic rays - that I hate) or abraid. Anyhow, I think your method is likely what really helps with preventing the knotted, raggedy thing.
