Doily of the Month and you can find the link to the pattern there.
This 6" doily was made with Aunt Lydia Extra Fine Crochet Thread in US sz 30 and my trusty US sz 11/12 crochet hook. The hook really does have that size beat into it! Must be old.
There's nothing like a blocked doily to bring out all the beauty it deserves. If I had a Like button, I'd like it myself!
