This is another 2 piece pix that I took of a necklace hanger someone had made of 1/2 inch rebar for the upright and and square iron for the foot.  There were 2 of these with a  3 to 4 foot rod hanging between them with the jewlery on it.  I didn’t ask but assume that there was spikes on both ends that go 8 to 12 inches underground.  Total height above ground was about 4 feet. Top hoop was 6 to 8 inches.
Cat needs something along this line to display her work.  Will see about making something along these lines to hold some bamboo rods.  May try to make a double hook affair to hold 2 rods at different heights.
