Drawabox is based on doing exercises to improve your mark making (the accuracy of the marks you draw on the page) and eventually leads to you drawing hundreds of boxes in perspective as a consistent exercise. A lot of people swear by it. I enjoyed the first week of it but decided that drawing is not a priority right now.

It is a good resource. Drawabox doesn't actually teach you how to rotate cubes. That was pretty frustrating to me.

I created a little game which doesn't explain it, but allows you to practice and get feedback: https://cdsb.itch.io/draw-cube
