I sketched many different possibilities for the holder: different shapes, slot positions, slot shapes, etc. As part of my sketches, I considered how the earbuds would be wrapped around each design, not just the design itself. In the end, I decided on the design pictured below--the circle with four slots around the edge, with the sand dollar pattern in the middle. I grabbed a ruler and decided the diameter should be 2.5 inches, a good size to hold in a hand and put in a pocket.
Is this a good/useful/informative piece of content to include in the project? Have your say!
