My daughter and I are prepping for Music Camp next week. She helped me make these easy pouches for our campers to store their take home games and activities.
What you need:
Zippered Pencil Pouch
Because the actual size of the window of my pouch was about the size of an octave on my piano, I just used the cardboard insert to "make a pattern" for my keys, instead of actually measuring. I placed the cardstock over my piano keys and made small snips with scissors in between each key. Then I centered the "pattern" in the pouch and lined up the 3x5 card along the "snips" to draw straight lines across the window. I love how forgiving the electrical tape is, but I thought some of the fun colors and patterns of duct tape could also make a fun variation for the piano keys.
