Having recently spent a small fortune on new bedding, I thought I could cut corners by using cheap pillow inserts; since the European shams were purely for decoration and didn't need to be comfortable. However; the standard size Euro, available at most stores, didn't fill the shams to the corners! I read a ton of reviews & finally settled on these over-sized inserts and am SOOO glad I did! It did take a little brute force to get them into the shams but once there, they fill them completely and look fabulous!!
