I have completed my Berroco Sox in the Heriot Watt colorway with lovely shades of blue and green. I used 72 sts and size 2.25 mm Addi Lace circular needles giving me a gauge of 9.3 sts and 12 rows to the inch. This yarn has a very long repeat of about 55 rounds. I like yarns, such as this one, with quick color changes. I get bored when the colors are very blocky and don't change for an inch or so. This yarn is 75% merino & 25% nylon which will make for warm and durable winter socks. I'm still wearing my summer socks and look forward to wearing these socks once our weather turns colder.
