The internet for Braille research and pictures. People with low vision/blindness for being cool enough to give Louis Braille a reason to invent this written language! For other forms of practice, I recommend writing in a diary or other form of writing. You don't even need a braille stylus or writer - just use a pencil to create the dots. In fact, if you press hard enough on a soft but firm surface (Such as a pile of paper) you will create raised bumps on the other side of the paper with just your pencil! You will both learn braille characters and your writing will still be legible! How cool is that!?
