You need a can opener to safely remove the top whothout making any sharp edges
Paint in a colour You want
Get some nice napkins
A Napkin has three layers, remove the two white layers, and keep the last one
Use decoupage glue all over the painted can (make shure the paint i dry)
Cover the can with the napkin while the glue is still wet.
Leave it to dry for a while, at least 15 minutes
Cover the can and napkin in more decoupage glue, so that the napkin is protected. For best result, You may wanna cover it 2-3 times with glue
It looks like very much, but when its dry, it Will turn blank
Put on some decoration. I had some bad luck with my napkin, so im covering it up with som decoration.
