After washing I dump my underwear thongs in a drawer until I need at the beginning of the day. Now and then I want a specific model and/or color for that day. I got tired of browsing through the heap in the drawer so I made a contraption to hang them in full sight.
It has 20 hooks but after I cleaned out the drawer, those 20 are my least popular thongs and strings. So I have tw hang two each from a hook. After attaching it to the door of my wardrobe, it worked as intended.
