Knowing all that I learned from the two previous hats made this an easy knit for me. The yarn is Anzula For Better or Worsted, 80/10/10 superwash merino, cashmere, and nylon.
A quick selfie for proof of concept. It fits the way I want it to. Now to work on a cowl version for non-hat wearers.
It’s coming along nicely. I’ll also need to work up a smaller version of the hat. And two options for crown shaping, too. So many options for this class project!
I’m writing the pattern in modular units (chart and written instructions) for each motif. And I’m trying to decide for the charts: a separate chart/page each for small hat, large hat, and cowl? Or just chart the motifs with instructions on how to set it up? That would take fewer pages, and that’s how I want to do the written instructions to avoid a 15 page pattern. It’s pretty obvious which motif you’re working, based on stitch count between markers. What do you think?
Onward!

Charming! Very cute!
Love it! Looking forward to the cowl.
I like the smaller whale fin on the cowl!
I love the whale tail. I think I chart with set up instructions makes sense. Thank you for sharing your process!
Very cute hat! I would want the motif charts and instructions as well.
The 2nd option with fewer pages. I’m ashtrays trying to figure out what pages to print out, I like writing all over the patterns. And I often don’t want all the pages.
