The form; also the arrangement, linkage, organisation and relationships of the constituent parts to each other that creates the form. So structure is as necessary in the management of the project as the weaving of one of the textiles.
In furnishings, and especially drapery and upholstery,the structure results from fitting and joining the different components of the pattern together The toile that creates this pattern has been wrapped, stretched, pinned, cut and tacked into place, and when it looks good cut into manageable sections that are shaped and annotated, to become ‘the pieces of the pattern’; when joined back together these make the final structure and form.
