It's a cute pattern, one that I've wanted to make, but I didn't have a little boy to knit for before now. I've decided to make a couple of changes, however. I'm not sure that I like the bright yellow, so it will be beige instead. I can always rip back and change it if the beige doesn't work out.

When I think of Calgary, I think of things like the Calgary Flames hockey team and the Canadian flag and the color red comes immediately to my mind.
