Zozee, I start in the middle of the block and make the bar-bar-square-bar-bar section. pressing the from the center toward the outside. Then when you make the top and bottom row, the seams have to be pressed in the opposite direction. Then when the top row is sewn onto the middle, I actually do use pins to push the seams together. I'm on my last ones, all cut out.
P. S. Don't tell (tee hee) Armylady, but I have some duplicate Australian Patchwork magazines I included for her in the box.
