Recommendation:For best results, your pillow insert should be larger than your sham to correctly fill the corners of the pillow cover, this will provide a very attractive firm and fluffy look to your sham, we recommend to place our inserts in shams that are 1" or 2" smaller than the pillow, It would depend on the thickness of the sham, a thick fabric would need a 2" larger insert to keep it fluffed, a more lighter fabric would need a 1" lager insert.
