I had some unused 20x20 pillow inserts for years that I had completely forgotten about, but when I found them I decided to get some covers to use them.  These covers worked perfectly and the color matches my new theater sectional.  Fabric is very soft and its very inexpensive as a set of 4.  I think the reason I never used the 20x20 pillow inserts is that I thought the pillows would be too large, but since my new sectional has enormous seats, all my other throw pillows look like pygmies so I'm glad I finally got to use them.  Glad I found covers for them at such a low price.
