Ingenious place to put your ukulele chord chart!

Can anyone think of a better place to put your chord chart when learning the ukulele?

Grace is a pupil at our school holiday programme who has been attending for two years. When she started with us she enjoyed the social aspect of our holiday programme but now she is playing more and more during our jam sessions and the busking trips. To see her progress like this is a satisfying part of the job. She is seven now and is playing all the time.

Grace showed me her invention this morning and I had to blob it and let the world know of the possibly the best place to place a chord chart for ukulele and probably guitar too!
