Very pleased with the inserts. I’m glad I got them 2 inches bigger than the pillow cover.

Fuller than most
As a rule when making a pillow cover you make it 1 inch smaller than the insert to give it density. But this 18x18 down insert fits well in a 19x19 or an 18x18 cover depending on the look you want. It does mention you should order the same size insert as the pillow cover. It’s not necessary to order up. It is definitely a heavier insert than a 100% down pillow. I was happy I didn’t feel any large quills which can penetrate out.
