Hmm, you need a face mask to get the nose metal from. Why not just sew new fabric along the same real face mask that’s falling apart? But it’d be germy and there was talk about not putting CV clothes in the washing machine so don’t see much good coming from this. Besides, you’d need duct tape to seal the mask to your face.
How about when you’re drinking your prepped soft drinks you save the can tabs for the nose metal.
“Sew ears to the face mask.” Ouch.
