When the dye dries and gives you the ombre effect...I would also let the kids personalize it with a sharpie or some nail polish art.

Create your own dip dyed shoes. You don't have to particularly use yellow dip-dye. I've tried this myself, and I dip-dyed my shoes blue and green instead. It really works! Make sure you have white shoes only, or else it won't work.
