The red one I crocheted on a plane just a few days ago. I love it that I can take my crochet needle to a plane—and I've taken it dozens of times—but they get all cranky about French cheese, because it's too gel-like. At least the Swiss security did. Anyways, I was thinking of a Japanese summer hat I had years ago which was approximately of same model, and I think I was also hoping to look more adult. Apparently that's not possible, though.
I started from the top and used ordinary crochet as long as I was increasing, then changing to this woven stitch I found in Betty Barnden's The Crochet Stitch Bible. Basically it goes: one crochet, one chain stitch, so that you always crochet on the chain stitch on the row below. I love the texture. Yarn is untwisted sheep wool from Estonia.
