Who knew that knitting required so much math? It doesn't, if you knit every pattern exactly as it's written. But, we all know that it's no fun to do that all of the time.
In this case, I really don't have a pattern. I have a finished sweater in mind. This means that there's math, and lots of it.
I was feeling pretty good about myself after I decided to knit this cardigan completely in the zig zag rib. "Easy peasy," I thought (with more than a slight hint of smugness). As I asked a couple of knitters what they thought of my idea, the warm glow of knitting joy left me to be replaced by the cold reality of knitting math.
As Grumperina so correctly pointed out, not only will I need to balance the rib stitches in the raglan decreases, but also the raglan decreases must happen at the same point in the ribbing series of both the sleeves and the sweater body.
Say what? Go here for a visual explaination.
Now, here's my problem with math, and it's always been my problem with math. I know how to do the actual math; but what math do I do? Then again, if that were never a problem, then everyone could be a mathemetician.
This is a challenge, and I'm feeling up to it. I've started a running log on paper to jot down my thinking and questions. My hunch tells me that because the ribbing of both the sleeves and the sweater body must be at the same point when the decreases begin, I will need to work backwards when planning the sleeves. That means that I need to know how many stitches the sleeves will contain at the point when they are joined to the body and the raglan decreases begin.
So, maybe it's less about the math and more about the counting.
