Waste not! Want knot (seamstress joke)! But a motto we attempt to live by! We often have fabric remnants from our other products that are just the perfect size for a lovely face mask. All of are masks are two layers and include a pliable nose strip for added shape and elastic ear bands. One size. Wash in cold water, line dry. Made in USA with lots of heart. Please leave us a note in the Order Notes field if you prefer a mask without the nose shaping wire.
