Simple.... get one pair needlenose pliers..... cut one piece of
coat hanger 4 inches or 10mm long..... make an  "L"....  the bottom leg of
being 1 inch (this will become the handle) ... now on the long end, bend a
small 1/4 inch or 5mm..... 90degree bend...... that's the key.... the other
end is the
handle.... now bend the handle end, into a spiral or half moon or what ever
fits your whimsy.... and this is the most important part... don't forget the
whimsy....paint with star dust and dry in a Caribbean breeze.. make 2 or
more, keep them in your glove box... Give the other one, to a needy camper
along the road ....
Happy Trails.
