Blank canvas, 2 diff color spray paints and choose a wall art sticker. Paint the canvas all one color then let dry and place sticker/arrange your design then spray paint all over again let dry then remove stickers and you have custom art!
Its a DIY project with just canvas,masking tape paint: tried it. A lot harder than it looks. paint bleeds really bad even with good tape. I ended up just using orange tape on white canvas and white tape on orange canvas (spray painted) looks great!
