Saved from myself!
As you can see in this picture, the right section of the front is worked over a single strand of yarn on one size of needles and the left section (which will be the center of the cardi) is worked with a double strand of yarn and a larger size of needles. So yes, I'm working with two balls of yarn and two sets of needles. And yes, it's REALLY annoying to work like this. I can kind of get into a rhythm with it, but it's slow going. I typically work both fronts at the same time when I do a cardi, but there's no way I could put up with that much going on at once, so I have to knit the left front, then go back and do the right front. After all this, the sleeves should fly.
Have a great weekend!
