For some reason I don't quite comprehend, I was feverishly knitting on George's second sock this morning.  I knitted at the first bus stop, I step onto the bus with knitting in hand, I knitted until the second bus stop where I continued knitting.  I knitted even while walking from my second bus to my appointment.  By the time I got to work, I had knitted to the heel start.  For that I need the book as I've only ever done one Dutch heel (on the first sock).  If this activity keeps up, George and I should have plenty of hand-knit socks.
