If you’ve got a pair of simple trainers and you want to renovate them or just pimp up, you’ll need masking tape, water, nail varnish. Masking tape off any sections you don’t want to get marbled. Pour a couple of inches of water into a container that is large enough to fit the shoe. First pour clear nail varnish into the water. This will create the base to marble the white on, but you will have to judge how much to put in because you can’t see it. Drizzle the white nail varnish over the clear and use a stick to marble the varnish. Read the rest of the tutorial here.
