Decide on your pattern. Print the floral pattern on the iron transfer paper. Use as many sheets as you need to cover the shoes.
Cut the paper in small pieces. You can trace pieces to fit the shoe, or what I found to be easiest was to cut around small sections of flowers and iron little pieces at a time.
Iron the pieces all over the shoes (following the instructions for your paper). Peel the backing off. Gently tap down any areas that aren't secure especially around the edges.
Replace the laces with something more fun, like leather, to go along with your new kicks.

Notes
Step 3: The iron transfer paper instructions will tell you to put a pillowcase or something thin over the paper while you iron, but that made it difficult to see where I was working. So I didn't really use it!After peeling the backing off, I tapped the tip of the iron on any areas that looked peel-y, and washed my iron afterward.
