This time with a non-labelled, sample ball of yarn given to me by my old employer. You can see what's going to happen here, can't you ...
I started knitting these ones the same length of leg I normally do (approx 60 rounds), but when I hit the toe shaping ... the remaining ball of yarn looked suspiciously small. Too small for my liking. I weighed the offending ball on my dyeing scales & was horrified by what I saw. A measley 30 grams. I weighed the sock (allowing extra for my needles). 45 grams. Clearly, this was not going to work.
I gritted my teeth, frogged the entire sock (after using a few choice swear words) & began again with fewer stitches and a much shorter leg.
The finished socks come in at 70 grams with a tiny amount over. So much for "assuming" this unlabelled ball was the full 100 grams I expected!
