This is how you get really smooth, lovely satin stitches. Outline in split or chain stitch, fill in the area with chain or long & short stitches, and then do the satin stitch. The underlying stitches support the satin stitch and help it to lay smoothly.
Lazy daisies are made from individual chain stitches arranged in a circle. Stitch up at A. Stitch back down at A. Do not pull the thread all the way through. Stitch up at B, just above A. Pass the needle through the thread loop.
