Using a 1/4" seam now and throughout the block-making,
sew Color 2 QSTs to opposing sides of the Color 1 3-1/2"
square, pressing seams towards the corner triangles. Then sew the last
two Color 2 QSTs to the adjacent sides of the center square, again
pressing towards the corners. This will be the block's center Square in
Square unit...on to Page 2!
