First off, I got all the way to cutting the pieces in half the second time, but then the trimming and final measurements I don't get.
So, I started with 11 in. square of sky and 9.5 in. of geese, and went through her procedure, arriving at the last bit, after you clip the seam in the middle of the square and press.
I cut the square in half, matching the quarter inch line with the tip of one of the geese.
What I don't get is how she uses a 12.5 in. square ruler to trim down the other three sides, and what measurement I'm supposed to be ending up with?
And secondly, how do I reason out the size of the two squares when I want a smaller flying goose? [I can manage Pythagoras.]
Thanks!
