I absolutely love Missouri Quilt Company and the excellent videos. Each time I watch one I'm running to the sewing room to make a block out of "junk" fabric for a test block. Then I mount the block to thin cardboard (cereal box) and write up directions to put in a plastic sleeve for my binder. Of course I add the name of the bock and where it's from. Can't tell you how many hours this has saved me when making a quilt. Thanks for posting the link to Exploding Block!
