After a bout of 2nd sock syndrome (lone alpaca sock that's been done for some time), I discovered a cure -- alternate knitting between two pairs. Here you see the poor alpaca next to an Opal Tiger sock in a purled ladder pattern. I am now working on the second alpaca sock and humming right along. Both are inspired by Sensational Knitted Socks by Charlene Schurch.
I've also joined the Mystery Sock KAL. Anyone else?
