Solve the rubiks cube blindfolded

i didn’t do it the “study it for a few minutes, close your eyes, and solve it from memory” way. i did it using a braille style method. just made each side feel different (you can use different sized tacs, or different numbers of little glued on plastic dots, or even different materials). then you can solve it by feel, and mix it up again, without ever looking at it. besides checking it when your done.
