These abstracts may be knotty, but they're completely SFW. :D These were all created using the Draw Curves tool added to Blender 2.78. Some are also using features from 2.79. Basically, these abstracts are testing grounds for trying out different features within Blender.
UPDATE: From the Blue overhand on are all from 2.80 Beta. Starting with the 5 Taut Line hitches, are ones from 2.80 Official.
I'm an Eagle myself :D Part of the inspiration behind this series ;)
As a former boy scout, I approve. These are all good knots. Nice work!
