in my BOM posts, i used a link to a flying geese how to.....well, it seems to have disappeared....so i'm doing my own, including the easy math. that way i know it'll be there when i need the link....
with the no waste flying goose (NWFG) method, you'll sew 6 seams and end up with 4 flying geese units that have no waste (duh), sewing no bias edges, and no edges that are biased.

here's the 'secret' math of the goose.
Quilter's Rule Quick Quarter and a fine tipped Sharpie to draw the lines. i test draw the line on a scrap of fabric to double check that it doesn't show through to the front, and is just dark enough to see. on lighter colored fabric i use a mechanical pencil with a light hand.
cut the unit apart by matching the edge of your ruler to the points of the large block.
i trim off the 'dog ears as i go. notice the top one is trimmed, the bottom still has it's dogears.
