crochet help?

[talluleh.livejournal.com]

Hi Guys,

I am pretty new to the art of crochet. I have mastered granny squares (woohoo!!) and I am currently attempting my first beanie which is a series of mainly double crochets. The pattern calls for front post double crochets and front post half-double crochets and I have no idea how to do these. Can anyone point me in the direction of a tutorial with pictures (or even better yet, video!!) I've been searching fruitlessly :(

Appreciate your help!
