I just turned a table runner this morning using Marti Michell's pillow turn method. Loved it! First, halve the back and sew it back together leaving a hole to turn in the center of the seam. Sew the top and backing together with a 1/4" seam allowance, press, then add the batting, trim the batting at the corners, and sew with an 1/8" seam allowance. Turn it, press, pin it, and pin baste it. It looks so much better than my other attempts when I sewed all 3 layers at one time.
