Freehanding patterns is HARD. Normally, and ideally, I would use a ruler for this type of thing to insure that everything is even. One of the most irritating things I think people say to artists, when describing their own artistic skills, is "I can't even draw a straight line." Neither can I. That's what rulers are for. However, I didn't really feel like it for this one, though, and was kind of curious what I could do by myself. So it's a bit off, but I don't think it's any the worse for it.
