hello,
I made a tutorial "arrows around a circle" very simple. (french video tutorial)

Those very narrow ones on the right look ok. But the wider ones look malformed.

Of course since I can't read or understand French, I can't follow the tutorial, to find out how you made them. I know there is at least one other message in this forum, about arrows in a circle, and probably a few, as I recall. This is one of those areas where there are a few different ways to do it, with Inkscape.

I dont speak french either, but it seems the effect is achieved with the Pattern along path LPE.

Interesting result, thanks for posting imppao !
