Many decorators recommend you size down your cover two sizes to ensure a full, overstuffed look. This is not necessary with our covers. Our covers are sewn to fit the coordinating sized insert. Using an insert that is too large could result in damage to the zipper.
20x20 covers are sewn at 19x19. Otherwise, the fabric will hang on the cover and look sloppy. This is to ensure the best look- full overstuffed and cozy as pictured in all my listings. All covers pictured in square sizes are sewn this way and stuffed with a 20x20 insert.
