This pattern takes the idea behind Kathy Merrick’s popular Babette Blanket, a blanket made of solid granny squares in different sizes, to its logical extreme. Perfectly Simple is a rectangle made up of nine squares in nine different sizes. In mathematics, this is called a “perfect simple squared rectangle;” perfect because no two squares are the same size, and simple because the squares can’t be separated into two smaller rectangles.
The original Perfectly Simple was a small decorative mat crocheted from sport weight yarn on a size F hook. This yields a 21.5” x 22” rectangle. If you prefer a more useful finished object, crocheting Perfectly Simple with worsted weight yarn on a size I hook produces rectangle of around 37” x 38” suitable for a baby blanket. In fact, you can use any weight yarn at any gauge you like and the rectangle will scale up or down perfectly. There are seven yarn colors; the yardage given above is the total yardage, which is divided unevenly between the colors.
