2. Set iron to the correct setting for the fabric. Press a 1/4" lengthwise seam along the 3" x 2" piece. Next, press a 3/4" lengthwise seam along the two 8" x 5" pieces, then a 1" seam along the bottom, widthwise (figure A).3. Using the sewing machine, sew on the wrong side along the open edge of the 3" x 2" piece, leaving a 1/8" seam allowance. Flip the 8" x 5" pieces over, so you are stitching the wrong side. On the bottom of both of the 8" x 5" pieces, sew a straight 1/8" seam.
