Seam Allowance

The strip of fabric between the cut edge and the stitching line.

The seam allowance is the distance between the raw cut edge of fabric and the sewn seam line. In quilting, a precise quarter-inch seam allowance is standard. Even small deviations — an extra 1/16 inch — compound across many seams and cause blocks to come out the wrong size. Many quilters use a quarter-inch presser foot to maintain consistency. After sewing, the seam allowance is usually pressed to one side (toward the darker fabric) or pressed open to reduce bulk.
