I have a Babylock Ellegante sewing machine. Amoung the many stitches is a piecing stitch which places the needle a scant 1/4 inch from the edges of my regular presser foot so that a special 1/4 inch foot is not necessary. However, the backstitch function doesn't work with the piecing stitch. I 'm wondering if that's because you're not supposed to backstitch when piecing quilts? Is this true? If so, if you make a mistake in a small portion of the seam (flipped seam allowance, uneven seam, etc) how do you fix it? Do you take out the whole seam and restitch, or do you take out only enough stitches to enable you to correct the error and restitch only that portion of the seam.? If it's the latter do you backstitch at the beginning and ending of the corrected area to secure the stitching? I'm referring to seams that are connecting two rows of blocks or patches.
