Face mask!

I love face masks, the cute little packets with face serums that leave my skin feeling relief in a way that applying a serum doesn't quite manage. But I hate buying all the disposal packaging and the mask never quite covers my nose or around my lips right.

Has anyone ever cut their own mask out of fabric and made a reusable version?

What fabric works best?

What do you use as the serum? I have a serum but cannot imagine applying enough of it to soak a mask would be cost effective, the one little vial is like $25 alone!

Just looking for ideas and advice! Thank you so much!
