InkStitch - fills with programmable stitches
Introduction
Ink/Stitch, as of summer 2018, provides support for four Embroidery stitch types: Lines, satin columns, tatami fills and manual stitches. Some embroidery software suites offer the possibility to fill in polygons with so-called programmable or speciality stitches, e.g. radial fills, hatches, little objects etc.
Ink/Stitch does not plan to includes these in the near future. However you can use standard InkScape functionality to create some of these. In addition, there are some extensions of interest.
Using InkScape Patterns - does not work
According to avmjong Bah's Inkscape manual, Any object or set of objects can be turned into a Pattern and used in the fill of an object. The Pattern can be shifted, rotated, and stretched as necessary. Inkscape includes a set of Patterns accessible through the Fill and Stroke dialog. One either can use built-in patterns or use your own ones.
Unfortunately, there is no way to translate a fill with pattern to paths since the pattern is considered a color. And, of course, Ink/stitch cannot handle colors as paths.

Other extensions, e.g. Generate from path -> Voronoi pattern are also using patterns as colors and cannot be used either.
