Missouri Star Quilt Company has a tutorial on the Herringbone quilt. It has no waste except the trimmings of the HSTs. I did a couple of layouts on the design wall and so far 4 rows to the right are all sewn. I had to web the side instead of the across the top since the blocks do not line up so my tape numbers go down the side, not the top. What I did is to take every other row (which have the same configuration) and do a leader/ender with those. After two sets of pairs sewn, I attached them together. I will do this for the rest of the quilt.
