I use the squares method. I know it wastes fabric but I can guarantee I'd waste a heck of a lot more fabric trying to do it with triangles and ending up messing up a bunch of blocks. I did watch the video mentioned above a while back and would like to try that method sometime. Is that video on youtube? That type of video never plays well for me (I can't seem to pause and let it load and even if I let it play through and try to watch again, it just stalls again).
