I will post the erratas here. You can also find them on Pom Pom's Errata page. The first one is in the very beginning of the Foot Section.
Foot: Round 1: K10 (12), [sl1, k2] 5 times, k8 (k10), k to end.
Knit to end, instead of purl to end, only for this first round. This insures a seamless joining of the two contrasting colours.
Leg: The round numbering is out of sync after Round 16 and currently reads from Round 11-39. All pattern text is correct but the rounds should be numbered from Round 17-49.
Cuff: Using the backwards loop method, cast 4 sts onto LH needle. Ignore turn work.
This should be Leaf Hand needle instead of RH. I'll revisit this again in the Lace Trim Tutorial.
The rest of this post is a tutorial on how to finish your sock with the picot trim. How to pick up for the lace trim will be in this second blog post. You'll need the lace yarn (Yarn B), a darning needle and scissors. So far, I have finished knitting the sock (excluding the heel). The last round of stitches is still on my knitting needles.
This pattern does call for double pointed needles. However, this time I knit this pair on a long circular needle using the Magic Loop Method. I used one 80 cm / 2mm Chiaogoo circular needle. I prefer to do one sock at a time. I also did knit the majority of this pair inside out. I cast on and did the toe as directed in the book.
I added a short-row to change direction once I joined my main colour (Yarn A). This allows me to kint my sock inside out. Follow the directions but knit instead of purl, purl instead of knit and slip stitches with yarn in front instead of yarn in back. I used some yarn I already had in my stash (shocking I know). I had plenty left over from Toft's Alpaca Fine Sock yarn from the original pair. You'll also recognize The Uncommon Thread's BFL, colour Attic Room, used in the Pennard Castle leg warmers from the book.
