About a decade ago, I lost most of my remaining vision, and needed to learn #Braille
Most of the resources (and training) are aimed at children with little to no reading experience.
Having been a visual learner, they didn't work for me. I couldn't connect numbered dots to letters. Math and writing are two separate processes for me. And don't mix.
So I created sheets to help me.
