I used to have a few website saved in my favourites that had free knitting patterns.. will have to have a look and see if they are still there... Just had a look and I dont have them anymore.

But... from memory there was one called knitty just google that and it comes up. The lincraft website also had a section with free patterns for knitting and crochet. Also a lot of the wool websites have free patterns too... for example Patons.
