Satin stitch can be used for outlines or fills. It is well-suited to borders and thicker outlines. It is also well-suited to narrower shapes where stitches run the entire width of the column. Satin stitches are almost parallel. Because there are generally no needle penetrations breaking up the fill, satin stitch creates a glossy, high-quality effect. Satin stitch can be used with any of the digitizing tools.
Puffy foam is commonly used to achieve 3D like raised embroidery. Digitizing for puffy foam might be a bit more technical that your every day digitizing, but if make sure you follow a few rules, it is actually not that complicated at all. Check out this article.
Use Object Properties > Outline > Satin to create thicker borders or columns of even thickness.
Use Object Properties > Outline > 3D Satin to create raised satin borders – can be used with trapunto for quilting effects.
Use Satin line to create thicker borders. Use 3D Satin line to create raised embroidery designs consisting of multiple layers of satin stitching. Stitch spacing and width can be adjusted before or after digitizing via Object Properties.
Use Select > Reshape to reshape an object shape, edit stitch angles, adjust entry and exit points, or customize envelopes.
Satin line width can be controlled either by means of the Width setting in Object Properties, or interactively, using the Reshape tool and dragging the sizing handles. When you drag them, a prompt appears indicating the line width, as shown below. Use the Offset setting if you want your satin line to overlap the boundary of the shape. This will stop gaps from appearing when using satin line as a border adjoining another object.
Stitch spacing is the distance in millimeters between two needle penetrations on the same side of a shape. Where it is very narrow, stitches need to be less dense because too many needle penetrations can damage the fabric.
Where a border narrows, stitches are tight, thus requiring fewer stitches to cover the fabric. The Automatic setting adjusts stitch spacing for satin stitches according to outline width. For objects of varying width, Automatic adjusts spacing accordingly. Manual spacing allows you to set a fixed spacing of greater or lesser density.
Stitch shortening is automatically applied to sharp corners to decrease density on the inside edge...

Satin fill is well-suited to narrow borders and shapes where the length of each stitch runs the width of the shape. Satin stitches are almost parallel, with every second stitch slightly slanted. Because there are generally no needle penetrations breaking up the fill, satin creates a glossy, high-quality effect.
As shown above, satin stitching can also be used for larger shapes where a glossy effect is desired. However, embroidery machines have a maximum possible stitch length which is determined by the physical frame movement. If a stitch exceeds this, it is generally broken into smaller stitches of equal length. The line formed by needle penetrations can affect embroidery appearance. The example below shows a hard line of needle penetrations where long satin stitches have exceeded the maximum stitch length. Usually 12.1 or 12.7 mm, this maximum value varies with the selected machine type.
There are two techniques for handling unwanted split lines - automatic splits and automatic jumps...
Auto Split breaks long satin stitches into shorter ones. But it also distributes needle penetrations in a random pattern so that they do not form a line down the middle of the shape.
While Auto Split is used primarily to prevent long stitches in wide shapes, it can also be used as an alternative to tatami fill. Auto Split looks more satin-like and works well with turning stitches, creating soft lines and a little more depth. By contrast, tatami fill is flat and can show unwanted patterns with tight curves.
Alternatively, you can apply Auto Jump to satin objects that exceed the maximum stitch length. In essence, Auto Jump is a means of preserving long stitches. It affects other stitching but is primarily used with satin. Long stitches are automatically divided into increments of maximum stitch length but without needle penetrations. To see the effect, you need to turn off Auto Split. In stitch view, the line down the middle represents jumps or 'needle up' movements at the maximum stitch point. Unless there are trims present, there will be a long uncut thread. TrueView shows long stitches as they will appear in stitchout.
Auto Jump generally makes stitching looser and subject to being caught and pulled and potentially broken. Thus Auto Jump can be used, for example, with manually digitized underlays which will be held down by cover stitching. It can also be used to create quilted effects, for example, by applying it to satin areas that are over-stitched with Run stitch or Motif Fill.
Typically, 3D Satin is used to create extra body in satin objects for visual effect and to provide a raised or 'sculpted' surface. See also Raised embroidery.
