I used a 10-inch blank canvas from an art store, but you could paint this design on a piece of wood or spray paint it on metal, too.
If using a canvas, I'd suggest brushing a coat of Mod Podge or acrylic gel medium on first; it will smooth out the rough surface a bit so the paint will be less likely to bleed underneath the tape. When the surface is ready, arrange pieces of tape and stickers to form abstract plant shapes. Burnish each piece with your thumbnail to make certain it's stuck down really well. Paint the surface (I used acrylic) and remove the stickers.
