Ah, skew lines—like trying to get my second block print colour to align with the first when the fabric shifts! Honestly, I’d just measure the closest points between two parallel guidelines I draw on my worktable, because in the workshop we work with physical parallels, not vectors. I should have paid more attention in class, alle? But here, my shortest distance is always a well-placed wooden ruler, because a real problem usually gives you a surface to cheat with, not pure air.
