I think I've decided that I love Doris Chan. She has a knack for designing crocheted garments that actually look feminine and that I want to make.
The Avalon Top (Rav) is a free pattern that's light and airy but still has substance because it's crocheted. I love the flower motif up by the neck and the frills at the ends of the sleeves.
Overall, I have some more slimming to do before I'd be willing to take this top for a test-drive, but I've got to say how it looks on the model is good motivation!
