Socks on top are knit with Trekking pro natura color 1602 blues and greens. Wool 75%, bamboo 25% with a nice hand, they knit up a little looser than wool/nylon.
The yarn for the second pair of socks is Mountain Colors Bearfoot in Goldrush. The colors are bright gold, cranberry, orange, purple and leaf green.
Both socks knit using my 2Sox2Circs pattern on US1 circulars.
