I recently just finished a project of a striped scarf using 2 balls of wool. They were both the same make, both 100g and only difference was colour. My conundrum is this why did one ball run out way before the other when i was using about the same amount of each…?
Yarn/wool is measured by weight (in this case 100gm), which is used to ESTIMATE the length. No two balls of yarn/wool, despite the same weight, will have the exact length. Variations in thickness (ply and overall), amount of dye/uptake and humidity will affect the weight and thus, the resulting yardage from that weight.
The only way to get exact lengths is to measure length, which unfortunatley, IMO, is not how manufacturers measure yarn/wool.
There should be a length measurement on the skein which tells you either meters or yards. What yarn and colorway did you use?
As Rochesterknitter says though it can be an estimate.
I understand this but such a huge difference when it is pretty much the same sort of wool seems a bit odd. there was a good chunk remaining but -shrugs-
can’t find the label or it now…got so much of all sorts of bits all over the place but then again it was cheap wool from a £1 shop
