A lot of apartments have ugly radiators that are hard to change. The best way here is to decorate them somehow to hide their unattractiveness. The simplest way to do that is to paint them with some patterns.
To paint radiators with your sketches you need to print your design on paper first. Lay a sheet of thin, clear acetate on top of the paper and cut the pattern with paper knife. To ensure that your decoration will be able to withstand the radiator’s heat, use special oil-based paint, not latex one.
On picture you can find sweet rocket decal-inspired flowers designed by South African illustrator Heather Moore painted on a radiator.
