Grace Ennis suggests Angora yarn be used for the contrail or smoke but I didn't have any and used plain white wool. It works and is MUCH less expensive.
Since all of Grace Ennis' Graphic Knitting Patterns socks are knit flat on two needles (or 1 circular as I did here) this is what the "leg" looks like before stitching up the back using the mattress stitch and starting on the heel flap.
I didn't knit the instep according to the pattern. If the design runs down into the instep, Grace wrote that you were to knit the instep flat as well and then stitch it to a gusset that was created without working in the round. I did it this way on 1 pair and didn't like that I could see the stitching on the foot. So, from then on, if a pattern extended into the instep I have been doing it in the round. This means TONS of little ends to weave in later and you also have to be very careful that there is no pulling or puckering. I may give the written pattern another go, who knows.
SNEAK PEEK: I have also been working on #7217 Triangle Overlay Socks and will post progress pics as they are available.
