If you don't have a lot of counter space in your bathroom, even something as small as a toothbrush can seem like it takes up a lot of room.
Hanging a toothbrush holder on the wall helps to declutter your counter, or you can hang it inside the cabinet to hide them from sight.
Photographer and Instructables user Andrea Biffi used one mini-pack of Sugru to make a really simple wall-mounted toothbrush holder. All you have to do is roll the Sugru into a cylinder, then press the toothbrushes into it and stick it to a vertical surface to dry. Make sure to wet the handle of the toothbrushes first—otherwise, they might stick to the Sugru and become useless decoration instead.
