I recently came across to a youtube video describing deco den art used on cell phone and DS cases. So i googled it and found so so amazing pictures, and not only they do it on phone cases but also on nails, rings, mirror cases........any surface possible........ The look is so cute and attracts attention for sure. One of the website that i found was luxaddiction.com The phone cases are bit expensive but really adorable.

Some of the amazing pictures of DECO DEN art that I found on Google image
