Lately I’ve been knitting in the round, which is exactly what it sounds like: You go round and round a tube and then you get a longer tube and then it’s done and you have armwarmers to wear to yoga.
Or say there’s a sweater you started in 2010 (last seen here in 2011). If you just keep going round and round you’ll end up with more sleeves on it, and someday a finished sweater to wear as a hiking layer.
Amazing how that works.
