A few years ago I taught myself to knit in the round on double pointed needles (dpn's) specifically to be able to knit socks. I hasten to add, that as an adult learner, knitting with dpn's was not a skill I acquired easily and took me a few attempts.
More recently I wanted to try out the Sirdar Crofter DK fair isle style yarn and initially chose the lichen shades of Glen #76 colourway. When I read the pattern I was surprised to find that it was written for knitting socks with straight needles not dpn's. I was curious about how the sock would be constructed so I decided to give this pattern a go. I should probably say now that I liked working with the Crofter yarn so much that I decided to make a second pair of socks right away but using dpn's in Galloway #73 shades of blue.
For the yellow socks the pattern states three pairs of needles - 3.25mm (US 3), 4mm (US 3) and 4.5mm (US7).
For the blue socks on dpn's I used the same needle sizes but I improvised a short row heel turn, used some of the pattern instructions and stitch counts.
I enjoyed knitting the yellow socks on straights and very pleased with the fit. The seams are positioned so there's minimum chance of rubbing especially the heel which has no seam. The only down side is dealing with a number of loose ends and sewing the seams. If dpn's are not your thing then this pattern might be for you.
For the blue socks with dpn's somehow the yarn balls didn't start with the same pattern sequence consequently I have slightly mismatched socks. I don't mind this so much because I really like the colours and they are going to be worn with hiking boots after all.
