Using up scraps

I've been on a mission to use up some of my leftover yarn. I've been making 7x9 squares for warm-up america afghans. The green and yellow are the leftovers from last semesters knitted toddler sweater. I've been trying to complete at least one square a week. Of course that's easier when I decide to crochet the square instead of knit it. It's been slow going, but I'm really starting to get a nice stack of squares.
