Finishing and Border

Join your yarn in any corner.
Single crochet (sc) around the entire blanket:

• Work 1 sc in each stitch across the top and bottom.

• Work about 2 sc along the side of each dc for even edges.

• In each corner, work 3 sc.

Join with a slip stitch to your starting sc, ch 1, and crochet another round of sc, again working 3 sc in each corner.
Fasten off, weave in all ends neatly, and block your blanket to shape. (It may appear slightly trapezoid-shaped before blocking this step will help even it out.)
