Part of Lesson 1 of Perfect Points at Connecting Threads was Flying Geese. I struggled a bit with peeks and narrow seam allowance. I was using a technique of cutting the pieces a bit larger, then trimming down to size after the section was made. We used a rectangle and 2 squares to make a section. I finally marked the center 1/4" seam on the rectangle and the corner 1/4" seam on the squares. Matching them up rather than matching the square to the sides of the rectangle gave me a nice seam allowance at the peak. BUT....I was concentrating so hard on that, that I forgot to pay attention to the side seam allowances. Those aren't so even. sigh.... Oh, well...I'm learning!
