Complete a split stitch outline around the shape and fill with split stitch padding. Bring the needle up on the inner curve of the shape just outside the split stitch outline where you can easily achieve the required angle for the first slanted satin stitch. Then take the needle down on the outer curve, just outside the split stitch.

Split stitch Padded satin stitch (split stitch padding) Slanted satin stitch

Bring the needle up on the first side again, very close to the first stitch, just outside the split stitch. Take the needle down on the outside of the curve, angling the needle towards both the previous stitch and the split stitch.

Work towards the end of the shape. To change the angle gradually, bring the needle up a little closer to the previous stitch on the inner curve and take it down a little further away on the outer curve.

The last stitch should cover the split stitch outline. It can be finished by threading the needle under the satin stitch.

Using a new thread, resume stitching where you started. This time the direction of the stitch should be reversed, so bring your needle up on the outer curve of the shape.

To change the angle, bring the needle up a little further away from the previous stitch on the outer curve and tuck it closer to the previous stitch on the inner curve.
