Plaiting is the process of interworking a number of skinny balloons such as 260s, 350s, and 130s, in a repetitive fashion to create a balloon fabric in any shape or pattern. Much like weaving threads to form a tapestry or reeds to form a basket, any number of balloons and colors can be combined to form an intricate creation. Plaited sculptures are often created as decorations to hang on walls, displays for rooms and store windows, and unusual costumes. All that's required to create anything imaginable is time and patience.
The instructions here are intended to be general with regard the specific type of balloons used. However, at the time of this writing, 260s seem to be the balloon of choice for plaited creations. Unless otherwise stated, it is assumed that the descriptions refer to those balloons.
