18cm x 18cm Please allow for some margin of error. Made with two layers of the same double gauze fabric on both sides. Double gauze becomes softer with each wash, and has a texture you'll want to touch all the time. 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.
