17cm across x 9cm to 15 cm extension from yo to bottom.
These masks are made with a double layer of fabric and has a pocket in between the two layers if you wish to place your own filter in. I have also left an opening for a nose wire to be put in if you wish.
The elastic is made from a stretch fabric and not rubber elastic and are made to tie around your head. This way you can adjust it as needed. Note elastic ties will vary in colour.
We are making these from 100% cotton and and the ties are repurposed spandex blends or from t-shirt yarns.
