I got some new variegated blue yarn, and realized it felt very 'watery' to me, which combined with the idea of using hyperbolic ruffles (and later, cilia) to become a waterfall hat. It was not easy: I frogged my first attempt at the ruffle, since it wasn't doing what I'd intended, and working on the second attempt felt a bit like I was exploring tentatively rather than having an already-decided plan. I'm pleased with how it came out, and realized just how much like water it is when I tried to take pictures: there are lots of possibilities for shape, more permutations than I can count.

(Also made in the last few months: hats with tubular crin (silver white flowers, the red and the black, mardi gras), hats with ruffles (hyperbolic blue, blue fascinator ruffle, and harvest ruffle), and hats with other decorations, such as stars, handles, amoeba, and fish.)
