Mailing it to yourself does NOT copyright. You are horribly mis-informed and your original animal throws have no protection, especially now that you have posted them in a public domain website. Anyone can copy them now. Additionally your instructions on how to assemble are really the only thing that can be copyrighted. The design of an animal quilt other people have already come up with (I've seen turtles and bears). Please do as the others have suggested and pay the fee and register them with the US copyright office. BTW this only protects you in the US. There are many foreign countries that do not recognize US copyright law and blatently pirate copyrighted material. Just so you know.
