There are hundreds of methods of tabbing and flapping paper and card. Some of them are glued, stitched, taped, or stapled and others are designed to interlock mechanically. Pull out flaps often have decorative shaping or other features. Corner flaps or tabs can be shaped and extended to create decorative shapes.

Simple hinges can be made in paper and card by using adhesive tapes, drinking straws, stitching, paper fasteners, rivets or by simple scoring and bending the card.
ADHESIVE TAPE is used by alternatively sticking it to the top of one side of the hinge and the bottom of the other; DRINKING STRAWS can be used to mimic an actual butt or back flap hinge; STITCHING like adhesive tape, proceeds from the top of one side, down in between the two pieces and then up through the opposite side.
