When you want to fill an area with a smooth finish, this stitch is the ideal choice. It’s best worked in small areas, because if the stitches are too long, they may snag.
Come up at point 1, then go down at point 2. Come up at point 3, then go down at point 4. Repeat. Always work the stitches across the area you’re filling, coming up on the opposite side where your needle went down.
