I hate Copyrightphobia, the fear of infringing upon somebody's copyright. I am upset by the Copyright Police. It makes me nervous when I enter a pattern in Ravelry that is a pattern derived from somebody else's pattern. For example, the Philosopher's House Socks, from Cat Bordhi's "New Pathways for Socks Knitters, Book One", inspired me to knit these:
The color is most accurate in the second close up photo.
I didn't use the yarn weight specified, so none of the stitch counts in the pattern were used. I didn't use the specified arch expansion stitch pattern, but made up one similar. I did use the Upstream Sock Architecture and Master Numbers from the back of the book. I would say this is a derivative work.
So, please tell me. Whose pattern is this? When I create the project in Ravelry, what should I use for a pattern name? Could I donate these socks to a fund raiser without having to ask permission? According to Jennifer Tocker's Copyright FAQ, this is a derivative work and I would hold the copyright on the derivative pattern, but Cat Bordhi would hold the copyright on the original design. But if I wanted to sell the pattern (I don't), would I give Cat Bordhi a portion of the proceeds?
I just want to have fun. Heck, I don't even want to go so far as reading Jennifer Tocker's Copyright FAQs, although I have browsed this very useful and informative web page.
