Cotton fabric and other fabric scraps, a set I don't see any damage or stains that would hinder use, but please understand that these are used items. I am an amateur, so I don't know the detailed material names, but I will answer to the best of my ability. Please ask any questions in the comments section. If you understand this, please read the profile section and consider purchasing. Images 12 and 13 are small scraps that have not been measured.
