I have some lovely Zitron Life Style merino sock yarn. BUT, I have never used sock yarn, and I didn't realize it was quite so "springy". I usually keep a pretty tight tension on the thread and lace weights I have used; do I do that with the sock yarn, too? Or do I keep a looser tension? It's for a shawl, so guage isn't too important, but I would still like to know what the recommended use is for this stuff. :)
