So for 6" flying geese I would cut a 7.5" square instead of a 7.25 and cut it twice across diagonally whereas for the 3" half square triangles I should cut a 4.25" square and cut it in half diagonally instead of the usual 3 and seven eighths size. Alternatively you could use templates and add generous seam allowances. I made mine from freezer paper as these can be ironed on leaving a good space inbetween for seam allowances.
Note that I still paid attention to grain line.
