Another tip for placing your fabric piece before sewing: Turn pattern face up and place a pin straight thru (vertically) the line where you are to begin and one pin at the end of the line. Carefully turn over pattern and place your fabric piece on the top pin and the bottom pin. This way you can see if you have enough for a 1/4" seam, and enough on the top and bottom to cover the area. And most importantly, you can see that after you sew the fabric piece down, trim it and fold it over, that it is covering the correct area! I can't tell you HOW many times when I first started PPing, I had the fabric placed on the wrong side of the line. The other important thing to remember, that any fabric piece that covers any edge, MUST extend 1/2" BEYOND your block cutting line. They say 1/4" beyond, but believe me, 1/2" is much better - Give yourself plenty of fabric for those edge pieces.
