That there is a ball of 100% Shetland yarn I picked up today. I love the stuff for its coarseness, springiness, and of course, sheepiness. I don't know if I'm ready to choose it as my favourite yet, since I just finished a pair of kilt hose inspired knee highs for my wife in bluefaced leicester which was also a joy to work with.

So what are your fav yarns and why?
