I started this sock and am in love with it. However, I'm not in love with the multi-colored yarn. It's Crystal Palace Mini Mochi in the Autumn Rainbow colorway. The yarn is a single ply but is a wool/nylon blend. I thought the nylon would make it stronger but not the case. I've already had it pull apart twice and have come upon a knot. Not things I like to discover while knitting a sock. I'm thinking that I'll do the foot the semi-solid off white.... K1C2 Crock-o-Dye. But it's a bummer since all the 'fun' of the sock will be under my pant leg. Ahhh well. I'll knit this pattern again with stronger sock yarn. 2.5mm circ / my own pattern.
