Lionbrand is a great place to find free patterns and tutorials too!
I've knitted several scarves, legwarmers (with and without cables, the one with cables was actually my first big project...)Made a ton of swatches with different kind of stitches.
And right now I'm knitting a blanket made out of different swatches of colours and stitching. (Mainly herringbone stitch, which is super fun, but eats up a lot of yarn)

I started out with crochet, mainly because I wanted to make amigurumi dolls.

Everything I do, is self taught with help of the internet.
