Hello there. I am trying to create a custom Iphone case using the services from a site like case-mate.com or getuncommon.com (has anyone used these sites before?). I would like the sides of the case to have that faux tortoise shell look that is common on eyeglasses (example: http://img1.etsystatic.com/005/0/6898462/il_fullxfull.385939301_jvj8.jpg). I was wondering if anyone knows where I can find or make a pattern/texture like this and if they can predict whether this will actually look passable on the case.

I appreciate all comments
