Here is my arrow design. I put them in box. I use a ellipse or half a ellipse in box, to do the bend. I also use perspective.

Very good explanation. I like the overall scientific approach with a dash of intuition. Quickly done. Twist and shout!

You explain everything so well Marshall, that I feel like I understood it right away. I was expecting to struggle a lot more then I did after all your warnings so was surprised to find out that it made immediate sense when I sat down to do it myself.

Excuse the messiness here,was trying a new pen and marker! will try some harder bend and twists to challenge myself later!

I found it quite difficult to smoothly transition from box to box so I tried 2d slices which seemed to work better. Having enough space between the boxes to draw in the transitions is also important.

Möbius strip :)

gave it a couple tries then came up with one or my own. Ben letting my lead dull out. I can do about half of what Marshall is using before hitting the lead sharpener. I will eventually make it work.

Marshall, It was a complete surprise to discover my arrow used as an illustration in this lesson, and I have to admit I’m a bit flattered—haha! I didn’t give it much thought when I drew that arrow, and now that I’ve seen and tried to follow your lesson, I couldn’t resist taking on the challenge myself—this time more thoughtfully. I hope I passed; it’s a very difficult task but so rewarding to develop this technique "scientifically" and explore this "P.O.V."

Decided to follow along with the video but without any filter paper or coloured drawing tools. If what you see looks like a mess then it is because it is one.

This is tricky

Mind-bending….had a go at mimicking the demo then tried chasing some boxes around the page with twist connections. Takes a bit of practice to begin to understand that the curves of each contour line twist and intersect in ways that are not immediately intuitive.

Here is a color-coded 3D model of the initial twisted form.

My attempts at bending and twisting and turning the arrows :) It keeps surprising me how satisfying it is to these exercises by hand, rather than digitally. I think, somehow, drawing things with pencil on paper allows me to accept imperfection easier.

I am still in the failing stage and I will be here for a while ;). I found this resource from a Proko student which is the 3D grid model of the rectangle twisting. I thought it was a nice extra to share with the rest and see if you are like me, that I am still trying to wrap my head around this https://practicedrawingthis.com/3d/model-twisted-box.html

Sometimes you are in the middle of something and you realize that it is going to be very bad. And you see all the flaws and mistakes possible in it. And maybe you start having second thoughts about showing the thing because it really makes all your weaknesses shine through. And did you even learn anything from doing that? You don't know. But you tried and that's gotta count for something. Message brough to you by: "How hard can it be" behavior.

I tried to do the twists intuitively without drawing boxes but keeping the concept of a box rotating at the back of my mind. I first drew approximately a simpler version like a ribbon of negligible width and then added depth and tracked the depth throughout using x-ray vision. The colored dots are added as the last step to double check if the edges of the box (imaginary) align correctly throughout. I think I have made a few mistakes in proportion, regarding keeping the width steady and in perspective. It looks right to me but my eyes are not much trained, though.
