Free Patterns

I love free knitting patterns. I've got a 3-ring binder that I keep all of my free knitting patterns. It's awesome. It's got dividers in it and is split up into several different categories, then the categories are organized by level of difficulty.
Anyway, I have several places I get my patterns. Most of my patterns came from Lion Brand's Website. This is an index of their free patterns. They also have a good Pattern Finder page. You can search it by keyword or by category. The categories you can search by include skill level, yarn, item type, size, and also what publication they appeared in. They also have free crochet patterns.
About.com is also a great knitting resource. They have an index of original knitting patterns, as well as a readers pattern library.
Lily's website has a few free patterns as well, though as far as I can tell, they're just the patterns from inside the yarn sleeves. Free crochet patterns here also.
And always a fan favorite, search free knitting patterns on Google.
I will also be posting all of these links on the sidebar by the end of the week.
Happy knitting.
