I am going to be listing several pieces of fabric. I will change only the title. I will list them as what I believe them to be. If you have a trick or technique for determining what fabrics actually are, please let me know and I can test them for you. These are all pretty good size pieces and there isn’t any damage to any of them. I haven’t sewn in years and I no longer know all of the various types of fabric. I think the majority of what I am listing will be rayon? Silky type fabrics, what I would consider great for sundresses or dresses in general.
