The pattern is from Simply Knitting Magazine, issue 157.
Luckily my trusty "Knitter's Handbook" came to the rescue. It looks a bit dated now but it really is an excellent resource for any knitter!
The stitch pattern basically involves working into the front or back of the second stitch on the needle, drawing the loop to the front of the needle, then working the first stitch as normal and slipping both stitches of the needle. Easy when you know how!
I'm knitting my socks in the recommended yarn, which is West Yorkshire Spinners Signature 4ply. The colour I picked is called Blue Lagoon. I've not used this yarn before, but I think I will buying some more as it knits up well and it comes in a lovely range of self patterning and plain colours!
The original socks are knitted in Passionfruit Cooler which is another gorgeous shade.
Hopefully I will be able to crack on with these soon and have some finished socks to share with you.
Also I'm on Ravelry, feel free to add me if you like.
