If you prefer to hang your Calamityware plates, you need a good plate hanger. Here's one that is completely invisible.
I tested one of these hangers. It works and it can be removed without damaging the plate (by soaking). Unlike those springy metal plate hangers, this is completely invisible—hidden behind the plate. You’ll find them for sale all over the web. The one I tested was 4 inch.
You could also probably DIY with some duct tape and a paperclip.
