Hi Jairo,

thank you for the suggestion.

Unfortunately, pens don’t work as patterns but only as outlines.

Unfortunately, that’s the same pattern over and over.
The randomization is only applied once.
Good for footprints, bad for fuzzy patterns.

Since I have more or less straight lines but of different length, the "one pattern per 1/n path segment" doesn’t work for me. I could try to construct my paths differently.
