I do pp with strips. I measure the width of the shape, so the ruler is perpendicular from the left edge of the shape and add on 5/8" if having 1/4" seam allowance. Then I cut strips this width. Line up the seam allow. with the new strips - right sides togeth. and sew. Iron the seam, flip the new piece over and press again, then go to the next piece, fold the paper pattern back on the sew line and trim off the extra fabric, leaving your seam allowance. This cuts your previous fabric strip off and gets you ready for the next shape. Take your next strip, lay the paper pattern on it, pin if necessary, sew, press, etc. It works so much better than trying to cut a shaped piece of fabric and get it big enough but not too big and have it be reversed. Yes, there is some waste that get's cut off, but I find it way easier. I learned this method from a book by Valori Wells - "Radiant New York Beauties". I've been working on a pattern now, that has 1/8" seam allowance and it works fine for even this small stuff.
