The pattern is Vanilla Latte Socks by Virginia Rose-Jeanes which is a free pattern that can be downloaded from Ravelry. I recommend this pattern as it is a great beginner sock, or a sock to knit when you don't want anything too complicated! It is simple to knit and has just enough detail to keep you interested.
I made the medium size which involved casting on 64 stitches, and the socks were knitted on 2.5 mm needles. The socks have come out slightly too loose so I think next time I will make the small, casting on 56 stitches.
The pattern is very well written and gives you lots of options. I chose to knit a knit 2, purl 2 ribbing as I think it the best ribbing for socks cuffs, and the stitch pattern for the leg is really easy too, as you alternate plain knit rows with a knit 6, purl 2 rib.
The pattern even offers three heel flap variations and two different toes.
I knitted the standard round wedge toe and then grafted the stitches together with Kitchener Stitch to close the toe
