In this tutorial, I will teach you how to make an Origami Flapping Bird (really flaps!) using a regular sheet of printer paper. If you have any origami or square paper, that would be ideal to use. Making the Origami Flapping Bird is very similar to making the Origami Crane, yet with fewer folds.
invitation for bid (IFB) A part of the sealed bid process. Companies or government organizations give in-depth specifications for projects and invite contractors to bid their proposals for various projects. The sealed bids are opened at the predetermined time and recorded. A contract is awarded to the best bid.
Contract document that describes the good or service to be obtained, and on the basis of which a procurement action is initiated. When combined with specifications, statement-of-work, and data requirement list, it comprises the procurement request package and forms the basis for an invitation to bid (ITB). Also called procurement directive.
