Capo transpose helper

Here I have a little helper for all the capo-players. Just download, cut out and find the correct chords. Please tell me if you find it useful.

You can download my helper with a cute little picture of my Stevens-Bouzouki at:

They have got a patent to this helper but gave me kind permission to leave it on my website if I mention the focuhl website. Thank you very much!
