I'm not sure of the exact fabric details, but these are remnants I've accumulated from a fabric store specializing in clothing materials. I'm selling them all together because I haven't had a chance to use them. As these are remnants, some pieces are cut (as shown in image 7), have markings, or minor imperfections. Therefore, although they are new, I've listed them as "near new." Please understand this before purchasing. The sizes vary and I haven't measured them, but I think they would be suitable for making small items. Thank you.
