I did some thinking, worked out how to do the head and here we have Hisssss
Hisssss by Fiona Hamilton-MacLaren
Yarn: Regia 4 ply
Needles: 2.25mm dpns
The tongue is a bifurcated I-cord (I really just wrote that here because the word bifurcated is great).
The pattern is up on Ravelry, but you can also find it in the summer issue of Sheepish. Really it should have had its own post, and probably will, but for now you can find it here. Lots of free patterns and other crafty goodness. It is a super socky special!
