Virginia, writer of Blackflipflops, took inexpensive silver plastic trays from the dollar store, added some chalkboard paint and embellishments, and ended up with an adorable note board that we love. This could be a gorgeous project to do with actual metal trays, as well---we constantly see them in thrift stores about town.
Virginia has added floral ornamentation (made out of pages from a book!) and wooden letters spelling "Notes." This is where you can get creative, or keep it simple, as we might be inclined to do. Either way, this is a DIY project that we just might actually do on our next day off!
