Cute idea - DIY hook rack for bags, purses, scarves, etc. Put this in the closet to hang the stuff that doesn't go on hangers? You can pick whatever knobs you want and just screw them into a piece of wood painted whatever color you want.
Door knobs come in handy when a hook is needed to hang a jacket or bag. Mount vintage knobs as hooks. Keeping the knob and the plate one color helps keep the hooks from looking too cluttered on the wall.
