Ombre tie dye - Apply a line of dye along fabric edge. Use a large wet paintbrush to push dye upward on fabric. Continue dipping brush into water and brush along edge of dye, pulling colour upward to create a gradation of the original colour.
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.
