Carol, I found the organza at WalMart. Since it was seasonal, I don't know if you could still get any. However if you are near a Wal Mart that still carries fabric, you might be able to find some in the sheer fabrics section. I really liked the effect it gave to the Christmas tree skirt. I would be happy to share, but I only have very small scraps, not enough to even cover the bottom I don't think of the 18x18 size you mentioned. I will check and see, if I do, I'll pm you and let you know. I am currently in the process of "cleaning or straightening" out my sewing area, so don't count on me letting you know for a week or so.
