It’s incredible some of the little details in LEGO instructions.

My son and I were assembling a set, and one of the corner pieces was strangely absent. My son asked, “why can’t we put this piece in yet?”

The answer came when we turned the page and saw the model had to be flipped. That missing corner piece was the only thing we could use to guide our placement of pieces on the underside of the model.

Similar things in more complex sets include using different, bright colours for bricks on the left/right sides of the internal parts of models. It makes it easy to keep your place as the model rotates through the steps.

The rotations and the color bricks are some of the most difficult to get right - and yet you never really notice them until someone points it out.
