I have this work in progess, which you can see is a pair of mittens with a lovely mountain scene across the front, all stitched in teeny yarn, several colors, etc.
Because I'm a glutton for punishment, I was attempting to knit both the right and left mit at the same time, because that's what you do when you're crazy-but-productive-in-your-head.
Somehere around that mountain top, I noticed that I had skipped several rows of the pattern on the right hand, so as you see it, I had to remove it from the suddenly-less-than-magical Magic Loop set up and trudge forth (or backwards, in this case...) one at a time, on dpn's.
My comfort level has gone up considerably, all of a sudden! Whew! No gigantic circular needle mess. Now here's hoping "second mitten syndrome" stays away long enough to power through...
