This is a simple, ear saver / mask extender pattern. premier home cotton is a cotton blend but I have made these using 100% cotton as well.

I tend to crochet loosely, so you might have to go up a hook size. I used a US G- 6 / 4.00 mm

Stitches we will use=
Foundationless half double crochet
Slip stitch
Half double crochet (hdc)
