The green cowl worked out fine.
After I finished knitting it, I didn't knit for about a month. Finally I ripped out the two projects I had languishing on the needles. They were a hat and a pair of gloves in patterns I'd never done before. I restarted them with patterns that are old favourites.
I withstood the temptation of a rather good yarn sale. When I say withstood, I mean I didn't buy anything. But I wasted a bunch of time putting yarn in the online cart, thinking about it, and taking it out. The waste of time counts as a minor cold sheep resolution failure for me. One of the points of the resolution was to take the time I would normally spend window shopping, and spend it on making things.
I ran across a good piece of advice on Ravelry. Someone said she wanted to knit a garment but didn't know what to pick. Someone else advised her to think about how long it had taken her to knit the last garment, then count the same amount forward in time, figure out what the weather will be then, and choose a pattern suitable for that weather.
Well! This advice would have me casting on for a wool sweater tomorrow.
