How about using thick, 100% cotton dobby weave fabric as a substitute for double gauze in mask making? Size: 33cm x 70cm (1.40m) Price is for one piece. It's a looped shape and double-layered, so you can use it like double gauze. 100% cotton, dobby weave, made in Japan. This fabric is gentle on the skin and is used for things like cloth diapers. It's new, but has been stored at home, so please refrain from purchasing if you are concerned. I have several pieces, so if you need more than one, please let me know how many you would like, and I will accommodate. Please note that the shipping method may change if the number of pieces increases. It will be shipped in a bag. Thank you.
