I had a custom made order to crochet for 11 doilies. They needed to be 45-50cm (18-20 inches) in size for a lady in Australia. She is going to use them for her wedding tables. Anyway, it took me about 40 days to make these. And, as usual, I changed the patterns to get the doilies to the size I wanted. I have pictures of 5 of these doilies so will post them for you to see.
