There's also a wonderful video on Youtube that I used to learn to paper piece.
http://www.youtube.com/watch?v=8uaW26igygE This made more sense to me than anything else at the moment and when I decide to paper piece a project I still refer back to this one to get started. I just print off my pattern from my computer onto regular copy paper, shorten my stitch length so it's easier to remove the paper when finished and piece away. I think this method is one of my favorites because everything is lined up for you and the blocks come out beautiful! By the way....your blocks are gorgeous and love the bright colors.
