One sock knit on the machine, using Trekking XXL, but not a perfect fit yet. The scale reads 46grams (from a 100gr ball).The remaining yarn (scale was zero'ed with an empty roll on it). It reads 48grams (yes, for some reason that does not add up to 100gr).
You know how swatches can lie? The scale can too sometimes. I would have totally not been surprised if I had started the second sock and managed to run out a few rows from the end! But, I had to rip the sock anyway as the fit was not perfect, and since it takes only about 2 hours to knit a sock (if all goes well, LOL), I wasn't going to put up with an imperfect sock. Especially since they'd already been knit once imperfectly and were sitting in the UFO drawer for two years, LOL.
