I think this is so delightful. It shows off collected plates which are not necessarily matching sets but look divine anyway.
It helps showoff pieces of furniture and adds definition to a corner or nook. I adore it.
An easy way to do this is to buy the stick on pads for the back of the plates instead of the plate grips that can damage the plate rims.
My son has a set of Royal Worster Camelot plates which would look stunning like this.
