I need to add something. I linked to the cake stands made by Iacoli & McAllister but didn't say all that I should have.
I was inspired by their idea and their cake stands are quite lovely. Each piece has a hand polished corian top, not a thrifted plate. ;)
They are definitely out of my price range but made by people, artists, and I should have given them more credit in my first post.
I didn't hear from anyone about this, just regretted that I didn't say more.
