Sfoglia or pasta sfoglia is puff pastry. A sfoglino or sfoglina is someone who makes it, and rolls it out in the old fashioned way (every year the city of Bologna has a contest for the best pasta chef, the Sfoglino d'Oro).
But sfoglini or sfogline (or sfogliaine in the Veneto) are also little pastries, which may be savoury ones for antipasto, or with fruit for snacks or dessert.
