6.7 Manual Darning
Used for darning holes or worn areas in all fabric types.
If the thread is lying on top and a poor stitch formation results, slow down the movement of the sewing
project. If there are knots on the wrong side of the fabric, move the sewing project faster. When the thread
breaks, guide the sewing project more consistently.
