some monotangles

Lately working on monotangles in one colour pen and shading with Prismacolours "Verithin"'s, new to me .
I tried out inverting the tangle, which I've not done before. I quite liked the challenge, but result wasn't perfect. But as there are no mistakes, didn't matter.

I think this is good way to learn the tangles, especially ones not used before, or very often, as me

with  'spinners'.
