I meant to say my working yarn.

My stitch yarn is fine. I've found that with all kinds of yarns I've used, like Lana Grossa's "Inserto" (my favorite) and others by lana grossa, Cascade, and then some of the cheap store stuff like Simply Soft. Im working on a bag with cascade wool yarn and the skien is center pull (the store where I bought them wound them into a ball for me for free). It almost seems like it twists more from the cnter pull then if I were to unwind it from the outside. And I find that all my thin yarn twist more then my chunkier yarn. I try to stay away from those "frilley" yarns, they look like a destastor waiting to happen in my hands.
Maybe it is my left hand knitting thats doing it. Any other lefties or continental knitters out there with this problem?
