This is actually wallpaper! Find it here.
So, where would one find such beautiful plates? Anywhere! Thrift stores, Ebay, yard sales, flea markets, Marshalls, antique malls, Target, Gradma's attic... The best part is that you only need one of each type! Also, don't be afraid to mix up shapes, sizes, and textures. Bowls are definitely acceptable and round tin trays are a great complement to a wall full of ceramic dishes.
I recommend hanging up your fancy finds with adjustable plate hangers:
They are easy to find at your local craft shop and some can even hold up to 30 lbs!
Disc plate hangers that can be purchased here and affix easily to the back of your plates.
You can arrange you plates in any configuration imaginable! There are no limits! Just be sure to know where you will be hanging each plate BEFORE you start affixing or nailing. I have learned that lesson the hard way-- too many times! A great (and safe) way to play around with patterns is to number each plate, cut out paper models (true to their size), and tape them up on the wall. Then you'll be free to experiment with different configurations. Once the paper cutouts are where you'd like the real plates to go, nail the paper to the wall, rip the paper off, and hang the plates! The pic bellow does a much better job explaining the concept...
