No, but ebay was a good idea. I just looked at 19 pages of rulers with 100 on each page, but no luck. If no one can come up with the website, I may have to try to draw my own. If I start with a 7" square, the use my scallop marker to make two sides convex and two sides concave, it may work. I'd rather have a ruler, of course. Thank you. I'll play with scrap fabric before I cut any batiks.
