I want to start a blog showing people how to make different crafts, art projects and food recipes. I don't plan on copying anyone else's work, but I'm sure whatever I come up with has been done before by someone else on this planet. I am only doing this to have fun and share with others. Can crafts, art projects and food recipes be copyrighted or patented? Is there a chance someone could come along and say they had the idea first and sue me?
