A couple of inspirations

Many thanks to Herman Hills Farm for demystifying the cut and sew hat. https://hermanhillsfarm.com/index.php/how-to-cut-and-sew-a-hat/

She worked out this technique through taking an online course with Olgalyn Jolly, who may be single-handedly keeping Machine Knitting alive in Brooklyn through her intensive workshops. 

Another issue is taming the elusive scarf edge curl. Her post on "The Elusive Long Stitch Half Milano Edge"  https://hermanhillsfarm.com/index.php/the-elusive-long-stitch-half-milano-edge/ lead me in some promising directions.

Applying enough time, creative use of available tools, and hard-won previous knowledge is still the path to success.
