I cut my green yardage for my second quilt, and it was just barely enough for the half chevrons and the extra HSTs (when not using the first method with the bonus units). However, checking my receipt I see that I bought 1 3/8 yd., whereas 1 1/4 yd. was specified in the intro, so those having just 1 1/4 yd. of green may come up a bit short if making the extra HSTs.
