This is very inspiring work, Mason! I am tempted to try it myself, using several different colors I have in the same type of yarn!
I have the Sweater Wizard, and it will give me a basic pattern for a top-down raglan pullover. I'm not as brave nor creative as you are. I mean that. Folks who can pick up a pair of needles and a skein of yarn and begin knitting and designing as they go....WOW. My hat is off to you!
I am happy to hear that this sweater is on its way to completion!
