Now speed piece the half squares, by stacking the
Color 2 and Color 3 2-7/8" x 5-3/4" strips right sides together. On the
back of the top strip, lightly mark the 2-7/8" square line and also the diagonals.
Now sew a scant 1/4" above and below the marked diagonal, pivoting at the square
line. Cut apart on the marked diagonal, and on the square line. This will give you four
half squares. Press the seam allowances towards the darker fabric. Trim
to measure 2-1/2" if needed...
