seam allowance

Seam allowance is the extra fabric distance between the edge of the fabric and your stitched seam. It provides space for sewing, future adjustments, or repairs. Typically, seam allowances range from 1/4 inch to 1 inch, depending on the project. Including a seam allowance ensures that the finished garment or item has the correct size and strength. When cutting fabric, you add seam allowances around each pattern edge, so when sewing the pieces together, there’s enough fabric to create sturdy, professional-looking seams.
