Thin material
The material is a little thin. Even though these pillow covers are lined with a satin type material they are still a little see through. I tried to insert another pillow I had that had a print on it but you could see the other pillow through it. If you use a plain while pillow insert these should be ok.

Cozy and Elegant
Love the fabric and the design. Elegant looking and cozy. I chose the light color to brighten up the couch. It’s a nice contrast with a dark shade of sofa, and gives a bright clean vibe with light colored couches. Made is of good quality and the zipper looks sturdy.

Nice and Soft throw pillow covers
The pattern on this pillow cover looks more luxurious in person than compared to the pictures. This is because there is a texture to it that is wonderful and is not very perceptible through a screen. It is very soft to the touch, and it feels good. Plush and padded. Easy care, I machine washed cold with white items only and hang dry. No wrinkles coming out of the washer.

Nice and soft.
Pillow covers are exactly as pictured. They are soft and fit well. The zippers are well made and the wash well. I wash mine inside out or in a mesh laundry bag. They don't shed at all which is great for me because I have horrible allergies. For the money, I would say they are a terrific find and I ended buying a second set
