Hi Ruthie,
You might want to get in touch with your state department for the blind. Most states will work very hard to get you whatever you need, or want, transcribed into braille. They probably have the resources to braille any deck you want. They would also be able to get in touch with other states for an interlibrary loan if they don't already have a tarot book in braille in their libraby. If you have some residual sight and can use computer programs like ZoomText, then you can go to
www.learntarot.com for a great course in beginning tarot. Just use ZoomText to enlarge the text to whatever size you need or to adjust the color scheme and brightness to fit your visual needs. There are also many computer programs that will read the computer screen to you. I work at a community college and we use a program called JAWS for our students who are totally blind. Both JAWS and ZoomText have many, many wonderful features. Adaptive software is making the world available to everyone!
