This is an interesting conversation. How do copyright laws apply to copying patterns out of a borrowed book (for your own use), I wonder? This came up while I was at a knitting store, and someone seemed appalled that a person wouldn't buy the book (as opposed to look for a way to borrow it.) I did not chime in at the time, but thought to myself, Geez, those books can get expensive. On the other hand, I noticed that my local library has quite a number of knititng pattern books, so it must not be illegal to borrow a book and copy a pattern out of it.
Do people often share published patterns on this forum (say, if someone were looking for a specific pattern in a specific book, but did not want to spend $30 on the book)?
