First of all, justflyingin you are amazing. That looks like the blocks are floating, gorgeous.
Welcome to the board where some of the nicest folks on the planet hang out. Missouri Star Quilt is a great place to look for layer cake patterns and Moda has some that will knock your socks off. As another member said just Google "Layer cake" and you'll be amazed at what you get. Skip the red devil cake with the cream cheese frosting, you can do that another time.
