Satin Stitch (free style)
Satin stitch is made up of straight stitches worked closely together (without overlapping) across the shape, as shown in the diagram.
Do not make the stitches too long, otherwise they are liable to be pulled out of position. Care must be taken to keep a good edge. You may find it easier to keep a good angle on your stitches if you lightly mark a clear line on your fabric, using tailor's chalk or a hard-leaded pencil.
