That is a blanket answer to the many questions I’ve been getting that all start with:
“Do you have a formula for [knitting pattern or technique]? ”
No, I do not.
Allow me to explain.
Many many many many (many) years ago, when I started high school, I took Algebra One. And just barely squeaked through it. Next year I took Geometry. That went marginally better.
Then came Algebra Two.
Sadly, our teacher died at the very beginning of the school year and we had a couple of months of a parade of substitute teachers who were little more than babysitters. By the time we got a permanent teacher, I was hopelessly lost.
(In retrospect, I wonder how I managed to pass Algebra Two. Because I did pass.)
Senior year of high school I took no math class.
Fast forward to my freshman year of college. In order to fulfill the requirements for my degree, I was required to take 3 credits of mathematics. I took a course called “Concepts of Mathematics” that was recommended for liberal arts students. There were pictures in the textbook. The professor who taught the course was, I believe, chosen for that duty by virtue of having drawn the short straw.
This is a long way of saying that I suck at anything that involves numbers and counting. The idea of creating a formula for something gives me a fit of the vapours and I have to lie in a darkened room with a cool cloth on my head until the mind-fugue passes. Like Mick Jagger, I have to turn my head until my darkness goes.
I know that other smarter and far less numbers-challenged people than I have come up with whizz-bang calculators for all sorts of knitting related stuff so I suggest you google for those.
I can’t count, either.
