Hey ! nice tutorial, thank you . Had a question, after making the concentric circle, how can divide each circle into indiviual path ?

Audio is not very clear and the music is very distracting!! The tutorial is very good though!!

Thanks! How can I create concentric shapes in "K-layout"?

Background score/music is not required, Please make tutorials without the background music.

Right but what if you don't know how many pixels and you start of with the biggest object?

I'm trying to do this with a more organic shape(a hand), but my attempt to scale the drawing is throwing it off. Any tips?

I am trying to create creative timeslice like danorst, this helps!

Remove the background music mate. Really distracting.
