I just got home from a little visit in my LYS and the owner surprised me. She surprised me with something that is very obvious but I never thought about. I had a Duh! moment.
I bought some knit-in elastic to knit into my next ribbing for socks so they stay up better and asked how far she thought I was gonna get with 200 meters and she started doing sums, used Pi and my needle size and how many stitches there are in one round and said I would need 4 meters for the ribbing. I was like "What?" and she said my knitting needle determines the size of my loop, obviously right?
So taking the circumference being needle size (in mmm) multiplied by Pi as a basis one loop will measure exactly this length. If you now multiply this by the stitches you have in one round and the rows you want to make you will get the meters of yarn you will need. It's so simple and so obvious, it's just something you never think about until somebody else is pointing it out. Just like bats have testicals too! Of course they do, they're mammals, but who thinks about bats in this way? I never did until I saw a picture that said out lound "I am male and I am proud" It's a bit off-topic but I think you know what I mean.

LOL :D
AntwortenLöschenI had never considered if male bats had balls...
But, I think the calculations are nice! So obvious and simple, but I had never thought of it... I guess this would work with yarn as well - if the yarn isn't too thick.
I thought about posting this tip on national pi day (March 14), but thought that it was too obvious. I guess not.
AntwortenLöschenWhen estimating yardage, you need to also account for the width and elasticity of the yarn. Thicker yarns have a bigger difference between the inside and outside diameter.
Haha. Bats have testicles...very funny analogy (did I spell that right and is it even the right word...Lol)
AntwortenLöschenBut about the math...totally confusing.
