Okey, dokey!
SO I got a chance to watch the video and agree, that is a fun way to make that block! I have practiced doing this before, but I couldn't figure out why I always had to "unsew" a few stitches (which they told me I would have to do, but still! <g>) anyway, the tip I picked up was: Put the 45 degree line on the sewn line ... almost makes for a dog-ear free block! Cool!
