Great intro, but. There are instructions on only some lower case, and it's out of alphabetical order. There are examples of upper case A to Z but no instructions. Yet, there are instructions and examples of the numbers.
If this was completed with instructions on each letter, lower and upper THEN this would be the most amazing guide, 5 stars, but sadly it's incomplete and out of order. Two stars because what is there is so beautiful, just not practical.
