this is how i learned to knit, they have the basic steps like casting on, binding off. also i learned howto knit and purl by watching videos on youtube. once you figure that out you can find a pattern on line by googling knit hat pattern and try some stuff out. i haven't yet figured out how to knit in the round yet as opposed to using two needles so that you dont have to sew up the back. but knittings stupid fun, and you can use thick needles to make thick knits which i prefer and it also takes very little time. gives me shit to do at work too.
