Digitizing - Underlay Stitches
Underlay stitches are manual or open fiii stitches placed underneath the top
embroidery stitches. The purpose of this “fiase" stitching is to secure the fabric to
the stabilizer, reduce the push-puii effect, and to prevent the top sfiiches from
sinking into thick textured fabrics.
There are two types of underlay stitches available in the PSW. The
perimeter/outline and the zig-zag stitch.
Stitch parameters
Underlay Density
To create different effects, the density of the underlay may be changed.
The value is in tenths of millimeters. The higher the number the less dense the
underlay. The lower the number the more dense the underlay.
Suggestions for Using Underlay
Satin stitches have a tendency to pull the fabric in toward the center of the
segment. For this reason it is a good idea to use the perimeter/outline underlay
for narrow satin columns.
For complex fill segments it’s a good idea to use the combination of
perimeter/outline and zig-zag underlay.
