I am confused today, so maybe I should just say how I make this block (either 2 or 3 color version).
For a 6 inch (finished) block, you will need 4 pieces that are 3.5" by 2" (These are the "geese") You will need 8 squares of, as I recall 1.75". Place a square of "sky" on the goose RST, sew diagonally across the square, fold it back on itself and press. Do the same with another square, to make one flying goose unit. If you don't have the right seam allowance, then take it apart and recut the squares. (I did say I have a headache, right?)
This is a basic flying goose unit. I know there are lots of good tutes here and on Utube for flying geese.
Don't let it get to you. Probably a step was left out of the instructions.
