Please help me think of a design.

My second cousin wants me to paint her shoes. She loves pink and Hello Kitty so those are the themes I'm going to use. I've though about doing a patterned look using Hello Kitty's face as the pattern. The way I see it, the shoes would be white then there would be Hello Kitty faces all around it, the faces would just be outlines and would be in pink. But I thought this wasn't something a 10 year old would particularly like. Any help would be much appreciated.
