That was a good lesson for week 4. Once I got the right measurement for the squares everything worked well. If you are making these exact be skimpy with your seam allowance or the flying geese blocks may be a little small. This is how I did my last set. I cut them oversized, adding 1/4" to each measurement (adding 1/8" would also work but it's easier for me to trim off the extra 1/8" than a 1/16"). So my cut sizes were 4-1/2" and 2-5/8".
I didn't like the extra fabric that got caught in the tips of the geese so I trimmed it off before sewing. Place the blocks on the corners of the larger square and measure the amount that overlaps.

For my oversized blocks I needed to trim 3/4" triangles off the tips. When adding 1/8" just trim 5/8". It is necessary to trim for the oversized blocks because some of that excess fabric may end up on the front of your finished block. Ask me how I know.

And if you are cutting exact and want to trim that excess, trim off 1/2". Place a square ruler as shown for this block size only if you don't have a triangle ruler.
