[Faith-talk] The Human Hand

Wed Aug 23 00:16:17 UTC 2017

It takes a lot of practice to learn braille by touch. I know exactly what you mean by having it upstairs but not being able to read as you'd like with your hands. I only know on contracted braille and can only read it with my left hand. I just can't feel the dots at all really with my right which slows me down and sometimes messes up tracking. I'm getting better slowly though. Just practicing reading helps. That's why I labeled stuff. I even braille at the top of mail that I have to keep like bills. I stick it in the braille writer and put on the top the company the date came and whether it was paid or not. It forces me to use it!
