Here's one I made Earlier

Storage Tins
Materials: Old Coffee tins, Spray Paint, Adhesive numbers.
Method: Remove label and prime with white spray paint, observe all the spray paint regulations and if you're doing it outside use an old cardboard box to create a 3 sided booth, use the extra side to place the object on. When dry apply adhesive number/letter/decal etc and coat with coloured spray paint, let dry and apply second coat. When dry peel off number to reveal first coat. Ta Da.

Other uses: outdoor candle, house marker, door stop.
Quote from the husband when I revealed my new project "Oh, you painted them." (Said not in rapturous tone of wonder. One word Philistine !
