I wanted to design a coat hook, but foldable and with magnet (because I love magnets). And I couldn't sleep. So... Here it is, in 3 versions ! A blank one, a supportive, and one to express your inner love toward your guests :D

The magnets are about 10 mm in diameter, and 2mm in height. There are spaces to put them, just glue them in it, making sure the polarities match.
