I'm with you.....self-taught, right to left, and marked my June Tailor with a sharpie when the measurements went left to right on the bottom and right to left on the top. And then.....through the years I've taken different colors of sharpies and marked cutting lines when they were weird ones that I had to cut a lot of and didn't want to keep figuring them out in my head, like the time I cut a bunch of fabric into 1 5/8" strips for strip piecing.
