What does the fabric depth adjustment do?
The depth relates to the height of the cloth lifter to the needle. 0 = farthest away ( thickest fabric) 6 = closest thinnest fabric) You are actually raising the cloth lifter. If the fabric is so thin that the needle hits or skims the cloth lifter or needle guide plate or doesn’t catch the bottom fabric, then a piece of tear-away stabilizer or tissue paper should be placed below the fabric. This will raise it for a good bite of the fabric and cause no damage to the machine.
