I'm getting into deisgning iPhone cases, but I'm not exactly super creative when it comes to ideas, I would love some suggestions. I love designing celtic knot patterns, my shop has 2 cases already, one I did for my Dad with his company logo, and one inspired by my son, Phoenix (which is ready for order). check them out at shapeways.com/shops/hcase. I would love any ideas, I am quite adept at 3D modeling and am able to incorporate anything I can think of, but would love ideas and suggestions from others. I am also willing to take custom orders, ie case style, designs, special logos, names, etc.
