I bought some white yarn (same brand) to mix with the pink/orange and blue/green yarn. Made couple squares with green/blue yarn. Couple squares with pink/orange yarn. Then, combined green/blue yarn in two directions, the pink/orange yarn in two directions. With the white yarn, used pink/orange in two directions and white in two directions. They are pretty squares. Eventually, when I run out of yarn, I'll have to sew them together!
