Interesting quandry here-I was criticized for sharing a pattern out of an old magazine with a board member, but it seams I would be perfectly ok to just send her the magazine.
Also, many people here sell old patterns (used or not) and that seems ok. At the guild meeting I attended, there was a "share" table with many books, patterns, etc. Free patterns are available all over the internet-I could go on and on! No wonder people are confused!!
