this is not a new trick but one ive been workin for close to 20 years.
this is an upcycled opalescent hobnail cookie tray and dessert dish made by anchor hocking. the pattern name is called moonstone.
it measures about 11 inches across.
both pieces (epoxied together) are in excellent condition. with no chips or cracks. simply one offs that were sentenced to the "stuff that no-one wanted box"
*** please note that the tray has an indent in the center and does not lay flat. the ruffles create an uneven surface. and while you can put a cake on it, I personally think that cookies, cupcakes or muffins would display best :)
