I love to make flying geese units. I prefer the old school one at a time method. I draw a line from corner to corner to stitch along to make the flying goose unit. Then I draw a second line 1/2″ closer to the corner. Stitch that line as well. It’s a bit easier to sew before you cut. I cut in between the two stitched lines. Use this method for both corners and you’ll have one flying goose unit and two half square triangles (HSTs). The HSTs are perfect for quilt backs! This is what your stitching will look like.
