Throwing the scraps & trimmings around is part of
Eleanor's schtick. Watch her tv show if you have a chance or if in Paducah for the quilt show, go watch her live. She is a hoot!
And no, I don't buy her rulers and the only wasteful piecing method I use is paper-piecing and that I use only for very complicated blocks.
If I like one her patterns, I go by the finished size block and add on seam allowances.
