Outside rounds:
Attach yarn to a corner space on the right, with wrong side facing you. Tr stitches worked into short sides of corners in round 1 create height so the work will be more evenly rectangular. Change colors as desired.

In the corner, work 3 dc, ch 2, 3 tr. 3 dc in middle space of short edge. In next corner, work 3 tr, ch 2, 2 dc. Continue working 3 dc in each space, finishing by working 3 dc in same space as starting 3 tr., hdc in top of 1st tr (replaces ch 2). Fasten off. Turn work.
