The Copyright FAQ for Knitters
I've been trying to work up a human-readable description of copyright and patent law, as it applies to Instructables. In my research, I found this really interesting resource for those looking to better understand copyright law, and to see how it differs when applied to various crafts. Some highlights:
A knitting pattern is by default copyrighted, but utilitarian items (clothing, for example) are not copyrightable.
You can make and give away items made from a copyrighted pattern. You may not make and sell items made from a copyrighted pattern.
A recipe is a process and cannot be copyrighted; only the expression of the recipe can be copyrighted. A patent is required to protect a process.
