Retro heaved: genuine 60s and 70s patterns available for free online
The great thing about the internet is how it archives stuff that should have been long lost. These old crochet patterns from the 60s and 70s been put up onto the web by someone very thoughtful, but the original site is long since gone and the thoughtful person appears to have wandered off. Luckily, web archives have come to the rescue, allowing us access to these fabulous old patterns. So if you're looking for some groovy inspiration (man), this link is likely to make you feel all fuzzy inside.
I've made quite a few things off here, and while I would never advocate the use of Granny Squares in clothing designs, some of the hats and scarves are proper groovy (did I do the "man" thing already?)
