Abstract: A variable tip pastry bag includes a flexible, conical-shaped bag with an end opening formed by truncation of the bag proximate the apex of the cone. The surface of the bag further is split a distance longitudinally from the end of the opening so that the size of the opening is variable. The edges of the split are adjustably fastened relative to each other, thus varying the size of the opening. A flexible connecting strap extending from one edge of the split, having a first fastening surface of a hook and loop fastener on its inwardly facing surface, and a connecting strap receiver attached on the outside of the bag proximate the opposing edge of the split, which utilizes an outwardly facing second fastening surface of the hook and loop fastener, may be used for fastening the edges of the split. A flap member is attached to the inside surface of the pastry bag and is formed to extend inside of, and across, the split, so as to preclude loss of icing through the split.
