Promising review: “This was such a nice addition to our rental apartment! A great way to add some color when you can't draw. Easy to install. The rainbow shape was the most difficult. But even I was able to complete it.'' “In the end! I asked for a sample song to practice with, and it was very helpful. It helped me get used to the technique!'' —Amanda farrell
