In the bathroom, there is a limit of hooks - and you might prefer to use them for clothes or towels. Over time, we learned the best solution was a
shoe-box sized clear plastic container. You can see what is in there making it easy to grab what's needed, when driving you can just leave it sitting on the floor or in the tub, it keeps things dry, they take lots of abuse, and if there are a couple of you - they stack well meaning a saving of space. Also, periodically, run them through the dishwasher to clean/sanitize them. IMHO, there are never too many of these - we keep all our stuff in the entertainment center stashed in these! I also suggest putting all those ancient clear Tupperware-type sandwich boxes to good use as they are great for stashing small tool bits-and-pieces, sewing needles and thread, etc.. Here's another good hint - you know those
cup-sized gum containers? Take an empty one, tear-off the plastic cover, and store your laundry/shower/toll coins in them - the screw-off lid makes it easy to grab the change.
