You can find more Arne and Carlos goodness including free patterns (some crochet, some knitting) on their blog:
I have their book, Knit and Crochet Garden, which is full of beautiful patterns (except for the dolls, I don't find myself at all drawn to their dolls. Something about the way they do faces...). If you're buying the book, check the edition (published in UK vs published in US) if you want to be particular about having UK or US terminology.
Note: links are in UK crochet terminology.
