Looking at the Vinkhuizen Prints, the scalloped lace has a round lower edge. I would paint “teeth” around the rim of the hat. The rear was easy, however, the forward sections made deep curves and the edges were not a distinguishable as the rear. Application became somewhat a hit and miss. As always, the second battalion is better than the first.
Note: In the photo (an in-between stage) the lacing was smoothed out to give a rounded and even edge during the touch up phase.
