From the Knit Picks Website:
This baby blanket is knit in-the-round from the center out, and finished off with a sideways knitted-on edging. There are eight increases every other round, producing an interesting spiral effect. And with the techniques used, the cast-on is only eight stitches, and there’s no endless binding-off, just grafting the beginning and end of the border together.

Size 8 (5.0mm): DPNs
