Next, we will inset the Color 2 corner
squares, starting along one side as shown at left. Use a scant 1/4"
seam allowance and sew to within 1/4"of the edge of the square.
Backstitch....KEEP YOUR NEEDLE DOWN and fold and pivot the square,
bringing it up to match the other un-sewn side of the inner corner.
Stitch with a scant 1/4" seam. Repeat this to set in the opposing
corner square...( If you have to take your needle out to get it to
line up right, that's okay, just be sure to start sewing at that
same 1/4" point, and not to catch any of your extra fabric in your
next seam) ...
