This doily is called Summer Fantasy by Fujiko Takagi. The pattern is in Magic Crochet magazine, August 1989. I really like the design and also the name :D It is done in triple crochet, and has some triple crochet popcorn stitches in the doily and in the last round. There are 25 rounds. I used about 260 yards of DMC cebelia size 20 crochet thread and a 1.25 mm hook. The doily measures 15" after being blocked.
