After crossover lace, which pairs lead pairs up and down the center?

• A. 1-1 2-1 3-4 4-4
• B. 1-2 2-3 3-1 4-4
• C. 2-2 1-3 3-4 4-1
• D. 1-1 2-2 3-3 4-4

Answer: (A)

The central idea is how the strands near the middle re-align when a crossover lace is tightened. The ones closest to the center move into positions that let the lace run up and down along the middle, while the outer strands stay paired with themselves to keep symmetry. So the inner strands end up pairing with their center neighbors, and the outermost strands stay with themselves. That gives the pattern: the first strand remains with itself, the second strands moves to pair with the first, the third moves to pair with the fourth, and the fourth stays with itself. This arrangement creates the intended up-and-down flow along the center after the crossover lace.
