wow, thanks! that only happens to me occasionally and I knew it must have something to do with how I held the yarn but I didn't know exactly what I was doing and when. that explains it! Now I have a rule to live by and I'll try to remember it. Some patterns it hasn't really mattered until I try to decrease but on this pattern I was doing some ribbing and it became obvious fairly soon.
Thanks so much for the advice ... I should probably only ever knit while sitting with a group of expert knitters so I can learn these things as I go!
Well, if Amy ever decides to do another magic loop video, I think she should include where to place your yarn when you change needles. I watched all kind of how to videos on knitting sites and on Youtube. I didn't find a single one that explained that. I had to muddle through and figure that one out myself.
I know --- it's one of those little things where they assume you know that, or it's such a strong habit it's hard to remember to put it in instructions. there always seems to be one tiny little part where I go "wait ... what?"
