I thought I'd share some doilies I just recently made as part of a bridal shower gift for a friend. The charted pattern for this doily can be found here, and if you have Ravelry, here is the pattern page. I love this pattern, and this is the second doily I've made from it.
I used Red Heart Classic Size 10 thread in Natural with a 1.65 mm hook. I tried very hard to keep track of how long it took me, because I always get asked that, so it took between 6 1/2 and 7 hours. If you try it, blocking is a must! Don't be scared if it doesn't look like it's going to lay flat when you're done crocheting... it just needs to be blocked!
This doily is the Pale Crocus (February) from Leisure Arts' A Year of Doilies. (Those with Ravelry, pattern page is here.) I used the same thread and a 1.5 mm hook. And I blocked this one as well.
I think they turned out great, and she said she's going to use them for the wedding!
