Not all sewing patterns are copyrighted. Having a sewing pattern you designed to be copyrighted can be complicated. First of all, you cannot copyright the idea behind a clothing pattern. What you can copyright only are the instructions and the images on the pattern. You cannot copyright anything, especially when that specific item is considered a useful object. That is why copywriting clothing design can get difficult. Clothing is a useful item, and copywriting a specific design can be tricky. That is because everybody knows that the main purpose of clothing is to cover certain body parts. And designing can change the external look of clothing but serves the same purpose. If you are a pattern designer, the only parts you can copyright on the pattern are the directions and phrases you originally made. You can also copyright the original drawings that you included in your pattern. When you want to pursue copyright for your sewing pattern, you need to check the database at the US Copyright Office website. Search for similar instructions or graphics to those that you want to copyright. If you find that your idea is original, you can apply for your copyright by filling out an application online. If your copyright consists mostly of images, you can apply for visual arts copyrights. But if it is mostly instructions, you should apply for literary copyright. Pay a small fee, then send two copies of the specific parts of the sewing pattern you want to copyright to the Copyright Office. You might have protected your work through copyrighting specific instructions and images. But it nowhere indicates that the person who purchases your pattern cannot make multiple numbers of items from your pattern. You also have no control over whether the purchaser gives, donates, or sells the items made from your sewing pattern.
