These socks are the Lichen Ribbed Socks pattern out of Nancy Bush's Knitting Vintage Socks.  I'm knitting them in Knit Picks "Simple Strips" yarn which is 75% superwash wool and 25% nylon.  I really like the colours in this yarn. 

I had actually completed these socks and then decided the heel flap was too long for my feet.  I've ripped one sock back and made the heel flap only 24 rows long rather than the 30 called for in the pattern.  Now to reknit the heel and foot, then I'll rip back the other one.
