design my own
 

If I design my own quilt, does it have to be registered or copyrighted?

Doesn't have to be... However, if your design is so original that you might want to protect it or sell it as pattern, you might check into copyright. I've never heard of registering a design.

You automatically hold the copyright to any original design as soon as you 'publish' it (make it public in any way). You do not have to use the copyright symbol or state that it is copyright protected, but you certainly may if you wish.

In order to legally defend it against copyright infringement (someone using your design for profit or claiming it as their own), it has to be registered. Here's how (it is, however, currently closed, as is the rest of the government, so you cannot register right away).

And here's everything (and more) that you ever need to know about copyright.

Thank you!
