Make the sketch space seamless
Because of the way the sketch space is created, there is a seam on the left and right sides which mostly, but don't quite align. This is also brought to focus looking up and down. There might be some considerations with how ink works. Consider a technique like: https://blog.spoonflower.com/2018/01/how-to-create-a-seamless-repeat-from-a-drawing/, where the seam can be moved around. This would require ~9 surfaces at any given time, which could be drawn across, the center plus up, down, left, right, and diagonals, but with the projection folded over.
