Its very easy. all you have to do is put paint in a small plastic cup, and very slowly pour it over the canvas. BTW it takes quite a bit of paint, but dont go overboard. If theres a lot on there it has a chance to crack and look even awesomer. for example, if its blue and it cracks there might be red underneath. mine cracked a bit but only cause i used a heatgun See More▼ unsuccessfully
