I bought some clear phone cases off of http://www.etsy.com for about $1.50 a pc. I found a really cute image of Baby Milo as the Avengers and I decided to draw that onto the phone case. I just used sharpies to draw it on and sealed it with a clear protective spray paint. It worked out great! Keep in mind, try to draw all the images on the OUTSIDE of the case. I wasn’t sure how this would turn out, so I didn’t want anything to rub or stick onto my phone.
