How to improve the shading effect of wooden shutter?

Add lining: Paste shading cloth strips on the back of the blades (cost is about 20 yuan/meter).

Choose wide blades: blades with a width of ≥5cm have better shading properties (narrow blades are prone to light leakage).

Double-layer design: Add gauze curtains on the inside to meet both shading and light transmission needs.
