Thanks for yout comments
@sfepa nice you like them. sure you will make good things with them.
@gra thanks for the compliment. The images (icons) were hard job, due the minimum size to display, but inkscape is cool for these tasks. now i am giving some inkscape training days to my timetable.
@flynsk yes, i think dedicated sets are nice , because you can have for example two ink brushes very similar, but tuning for different purposes.
