18cm x 18cm Please allow for some margin of error. Double gauze, two layers. No edge stitching, hand-sewn opening. Double gauze becomes softer with each wash, and has a touch you'll want to keep touching. This is a handmade item by an amateur. I hope to sell it to someone who understands. I am not considering individual price reductions for handmade items, so please take advantage of the discount for bulk purchases.
