Thank you I'm glad you both like my knitting!
pinzneedles, I used Hipknits 4 ply sock yarn for the lower single sock (the second is now finished so I must photograph it), and Fiberspates 4 ply sock yarn for the pink and green mottled pair. I don't think you'll be able to get that exact colourway in the Fiberspates and certainly not in the Hipknits because they're no longer made in that colourway - but some of the other dyeings are just as nice!
