Here is an adaptation to the shawl, if you don’t like so much ruffling and/or want the yarn to last a little longer.
Work Rounds 5 and 6 twice, working into the ch-5 spaces as needed. Then work a Round 7. If you want to, it might even work out with yet another repeat of Rounds 5 and 6 (that is, you’d be working Rounds 5 and 6 3 times before working Round 7, which is the Dogwood round). I am experimenting with it, and it seems to be working out fairly well.
