Baby Blankie

The sweater I was working on has been put on hold for the last couple of months to work on a baby blanket for a former coworker. Several of us at work put our money together to buy the blanket, and one of the girls wanted to learn how to knit, so she's making one stripe and I've done the others.

Now I'm trying to decide whether I want to put the stripes I've knit together to form diagonal squares of color, or more randomly. Any thoughts?
