As they say in a current UK TV ad 'One (Juan) sheet does plenty'.
Below are two files that contain the up and down patterns for the first twenty Hanon exercises. You can download and print them on one sheet of A4. This is very useful in terms of portability, but certainly isn't pretty, so I'd definitely encourage you to get the full version.
Please feel free, if you're a Hanon enthusiast, to leave recommendations and tips about Hanon usage. I'll start it off with one of my own: practise them in E flat.
