Tried experimenting and ended up reinventing very basic techniques that already exist and that I already understood. Shrug.
The bottom triangle was to test out the raglan line increase with Judy’s magic cast on, increases were simple yarnovers done one stitch out from the center line. Turns out Judy’s magic cast on is completely unnecessary if you’re not knitting in the round. So for the top triangle I skipped the magic and just went with a normal cast on, this time yarnover increases at both ends of each side (i.e. along the center line and at the edge). It made the basic shawl shape, which in retrospect should not have been surprising, but was definitely not what I was aiming for.
If it matters, I was wondering if I could use Judy’s magic cast on method to begin the side seam of a sweater knitted on the bias that creates front and back at the same time. Obviously it would only work for one side seam and the opposite side would have to be sewn up like normal, but I overlooked a lot of details when I came up with the idea (in my defense, I was half asleep at the time).
I could probably adapt the top triangle attempt to my intended purpose if I began it at the armpit or something and remembered to continue the bottom triangles for front and back separately once I reach the bottom edge of the side seam. And I think the bottom triangle attempt could work for a short sleeve shape for set-in shoulder. Which would look silly wouldn’t it? Adding a raglan sleeve to a set-in shoulder? Yeah maybe not.
