Drawers are the best places for utensils and small stuff. I get plastic trays of different shapes and sizes to fit in my
drawers at Dollarama or Dollar General. They work well for most stuff. I also use them under my 3rd seat as a
tool drawer organizer too, for wrenches and screwdrivers.
There's a rubberized shelf netting that helps keep stuff from sliding around, that works on larger surfaces,
but if something is heavy enough, and has developed sufficient inertia, it'll be moving unless somehow secured.
Some stuff can be secured with "sticky on one side" velcro pieces. Put one piece on the object, and one piece
where you'd like it to stay, press them together, and it may work. You might find it at Walmart or someplace like that.
Good luck, it's a problem we all face.
