I made a bunch of spun out bowls with cookie feet that I would like to hang in a cluster on the wall (the first picture is them lying flat on a table). I’m not sure how to hang them safely. As you can see, they are pretty transparent so any hardware would be visible. Has anyone done this before? My friend has a 3D printer and offered to make something to help mount them but I’m not even sure what that should look like. Thanks!!
