Areas of satin stitch can be raised by first working a foundation of padding. This can consist of rows of stem stitch, chain stitch, or running stitch or if you want a very raised effect satin stitch can be worked over thin felt or depending upon the use of the item you are working, even card.
Work the padding first, in the illustration I have used a few long straight stitches. Cover this padded area with satin stitch. Be careful to completely cover the padding. When completed only the satin stitches should show.
Stitches related to single satin or straight stitch in this dictionary are Satin stitch and Padded satin stitch.
