If you're into knitting and vintage, there are many great online resources for free intructions. One of the best (IMHO) is the Victoria and Albert Museum's 1940's collection.
Scarfs, hats, jumpers and so much more. Even fishnet stockings! And it's not all just for women, there are patterns (mittens, pullovers, hats...) for men too! So, if you're into vintage knitting, this is a must see.
Go ahead, knock yourself out! ;)
