This was knitted on cocktail sticks to start with and GarnStudio Fabel Sock Yarn which I absolutely love. I got annoyed with the cocktail sticks after the 3 rows of ribbing (they were cheap ones and even though I'd sanded them down with an emery board they were still too rough - Note to Self: buy good quality cocktail sticks next time.) so I switched to 3 x 2mm and 1 x unknown size of DPN. According to the video I watched online EZ says that you can use 1 dpn that's a different size to the others and that the difference in gauge with even out as you knit the sock - happy to report she's absolutely right!!
Isn't this lovely? I'm going to turn it into a Key Ring for one of my Swap Buddies although my sons both wanted to have it and were absolutely fascinated.
