These 4 doilies have the same pattern but 2 are 9 inches and 2 are 10 inches in diameter. They are snowy white and have no damage of any kind.
The center is swirls like pinwheels surrounded by rows of single crochet. The border is shells with picot finish.
Not sure of age. I've had them a long time but they are so snowy white they may not be terribly old. The doilies are made with quite sturdy thread and tight stitches. They are heavy enough that they could be used as hot pads except on very fine wood finishes.
