Review on 🏨 Hotel Quality 2 Pack Standard Cotton Sateen Pillow Protectors - Hypoallergenic, Zippered, High Thread Count 400, White by Will Jenkins

I bought these fabric covers to make Covid masks. The description implied they were woven very tightly to keep the fluff from falling out of the pillows. And this dense weave is just right for masks. However, they didn't look any better than any of my other pillowcases and may not be as good as some. Held up to the light, you could still see the light through the fabric. This is a mask fabric test. I suspect this is a similar test that can be used to check the weaving of a pillow's down. For this reason I ended up sending them back and will continue my search for heavyweight cotton fabric.
