The first thing to do, before even buying the shoes, is to have several ideas and draw them on paper. Sketching and coming up with a design is the most important part. You also have to take a careful consideration when buying your shoes, the most important factor is the fabric and color. Do not buy leather shoes, or shoes with a lot of texture. If you buy white or light colored shoes you can use fabric markers to color your art, giving it a smooth natural look.
