This test is with two layers of batik, testing ribbons and elastic. I like a thicker (3/8″) ribbon over the thinner (1/4″) and I much prefer the sewn channel along the side versus leaving it open, which is what I tried at first.
This is a double layer of batik fabric that was very comfortable to wear. It has the “pocket opening” at the top and the molded nose-piece.
I also prefer sewing the ribbon ends versus tying them and I really like this wider piece of elastic (1″ wide) I found in one of my sewing bins. It slid comfortably on and off and held the mask in place very well. I cut 7″ and sewed the ends closed, leaving enough room to thread the ribbon, attached to a safety pin, through.
