The green one (made according to the directions) measured approximately 7 inches across and that was too small for my liking.

The orange one was made a little larger (aprox. 8.5 inches across), but the ruffles became too much.

The pink one, though, was juuuuust right. I followed the directions in the link, but after round 9, I crocheted a round of single crochets (just one stitch in every half double crochet stitch below). Then finished it off with a round of slip stitch in every single crochet stitch. This cloth measures 8 inches across and the last two rows of single crochet and slip stitch in every stitch settled the ruffles down so that the waviness is pretty perfect.
