The last three weeks I have been knitting on my commute ever since I read somewhere that knitting 4-5 rows here and there add up after a while. It is so true. One evening I was able to knit 24 rows just waiting for the bus driver to finish smoking his cigarette and the 6-7 stops to get home. It helps make the commute go by faster as well.
I must say I was a bit self-conscious in the beginning but people just smile. One lady struck up a conversation about how long I had been knitting and stuff. Yesterday I met my first knitter sitting across from me; we nodded at each other and smiled.
I love working with circulars even though I am knitting scarves. This way the needles are not getting in people's way and if I drop one it stays with me, not on the floor.
