Unvented. Inspired by Barbara Walker's dragon skin pattern. The basic stitch pattern of http://www.ravelry.com/patterns/library/lacy-dragon-large-scale-washcloth and (if the double decreases are done as sl2-k1-p2sso) http://www.ravelry.com/patterns/library/dragon-scale-shawl-upscaled
The overall pattern is basically Walker's Shell lace with a half-drop. (If I had realized that early on, I could have saved a lot of time.)
Shown with a cast-on count of 67 stitches.
