The challenge was to do the Zentangle ONLY with your non-dominant hand.
I did the whole thing with my left hand but when I went to fill in the solid black areas I just couldn't do it.
So I cheated and filled them in with my right hand, therefore wrecking the whole concept.
I never was much of a dominatrix!
