Vintage square lace tablecloth, all handmade, cotton thread lace crochet in a pinwheel pattern. It's about 52" x 52" overall.
This has been used (and mended!), still has a few unstitched joins and some spots which I have not tried to remove. Shabby but pretty, an unusual design. It looks to me like a hard pattern to work, and must have taken weeks if not months to make.
