Prepare the shoes by removing the laces and taping areas that will not be painted.
Load the brush with water and soak the fabric of the shoe.
Mix the water on the shoe with about five (5) drops of Fuchsia to create a watercolor effect. Dab lightly onto the fabric of the shoe. Do the same for Turquoise and Purple, randomly adding watercolor blotches around the entire shoe. Allow to dry completely.
Using a very small, round brush, draw octopus on the side heel of the shoe with Black. (Use a dabbing stroke to apply paint to get into the fabric.)
Paint the tentacles around to the front and the other side of the shoes. Allow to dry thoroughly. Remove the tape and re-apply the laces.
