(4) 2 1/4" squares for the flying geese background
Step 2: Draw a diagonal line across the wrong side of the (4) 2 1/2" squares. My favorite method for speeding up this process, especially if I need to mark many squares, is to line up the points of the squares along a line on my cutting mat.
Step 9: Stitch on each side of the drawn line. (I've enhanced the stitching lines on my photo just so that you can see them better).
Step 10: Cut the units apart on the drawn line.
