Recently I moulded most of my doily collection into little plates and bowls. Each doily is dipped into Plaster of Paris and is then coated and gently baked with a layer of sealant. This makes the delicate dishes slightly more robust and water resistant.
They look good used as tea light holders, hung on a wall or placed on a shelf. Many of them are for sale at The Caboodle, and I'll have a batch at the i♥market too.
Here's a delightful definition to enjoy:
A doily (or doilie) is an ornamental mat, originally the name of a fabric made by Doiley, a 17th-century London Draper. Doily earlier meant "genteel, affordable woolens", evidently from the same source.
