Motif fills are similar to regular
fills. You control the density and gradient. Motif fills can be curved as with
regular fills. In motif fills, the traveling stitches always run along the edge
so as not to interfere with the motifs. The motifs are added in the same manner
as motif runs.
The density adjustment in motif fills adjusts spacing between each line in the fill. A zero value here will cause each row to just touch the previous row.
Please see the Motif Run section for details on the use of motif controls.
