What is the shape and size of the holes to be cut in the black mesh liner?

• A. Six 2-inch round openings
• B. Eight 1-inch square openings
• C. Ten 1-inch square openings
• D. Four 1/2-inch square openings

Answer: (B)

Think about what the liner needs to do: it should drain and vent while keeping items from slipping through. Eight openings, each 1 inch square, strike a practical balance—large enough to let water and air pass, but small enough to retain typical gear. The square shape works well with the mesh grid and lets you cut cleanly with predictable edges, making the layout easy to reproduce and the edges less prone to fraying. Spacing those openings evenly around the liner provides uniform drainage and avoids concentrating stress in one spot. The other options either use holes that are too large (risk items escaping) or too small/too numerous (hindering drainage or weakening the fabric).
