They are sheer panels. Light does shine through. My pictures are from a cloudy day, however. I ordered 4 white color panels for $5.99 each. Very pleased with the product for the price. Exactly what I wanted. Shipped within 48 hours to my door. I ordered the 54 inch by 84 inch, and they cover my windows 57 inch wide windows as well as the five inch wide trim around the windows very well. My curtains are obviously still wrinkled from being in the package.
