After pondering on that picture and this thread while working this afternoon on the shawl I'm making...
About this thread:
I encourage you to find a basic sock pattern and give it a go. GG's Lifestyle Sock is a great one to start with.
I'm far from the most skilled knitter in the world, but to learn the basic skills needed to knit a variety of projects, knitting one plain stockinette pair of socks top down with a heel flap and gusset, with a double decrease toe probably gives you the biggest knitting techniques bang for your buck, so to speak.
After watching this I felt confident enough that I really could do it that I cast on immediately. This is the link to the tutorial. Its on 2 pages with the first lesson on the 2nd page. Unfortunately when KnitPicks changed their site the tutorial was reversed. GRRRR! Still worth watching, though.
About the picture:
There are multiple ways of making sock heels and that I can't quite identify a type of heel from the picture or the instructions bothers me a bit.
Like you, I look forward to seeing what GG chooses to add to her growing list of projects when it's completed.
