  Start weaving:
  Using a weft thread of flexible material which goes well around the warp thread, the weaver carries out a first passée from right to left, taking care to leave the threads free at each end so that they can be used to check that the width of its fabric is respected.
  
  These threads are called: “guide threads” (fils guides).

Technical Drawings

The drawings have been executed in such a way that the passage of the threads is understandable and highlights the process represented. These drawings do not show the real appearance of the tapestry fabric where the weft threads must be packed down in order to completely hide the warp threads.


	Duite, feminine noun. Set of two passes (passées), that is to say a movement of left to right then right to left of the weft thread through the warp, generally perpendicular to it. The first passée covers a layer : after packing, the warp is completely covered on both sides of the piece. Duites rarely extend from selvedge to selvedge : they stop at the outline of the drawing or are limited in the monochrome parts by the material conditions of the work.

Weaving Defects and Deformations

Curving of the warp: warp deformation due to an irregular tension of the duites.

Wrong passée : duite whose return passée covers by mistake the same warp thread as the previous passée.

Curvature: this is a localized narrowing inside the warp along a relay.

  Oblique line with a steep slope. To obtain this type of oblique line, you must superimpose the duites by making steps of one to several duites. On the graphs, we made the oblique lines by shifting each duite by one warp thread (graph 1), or, by shifting by one warp thread and superimposing three new duites (graph 2), until the line is completed.

  The curves.
  
  Concave curve. This arc-shaped curve results from the superposition of decreasing levels and steps of one duite.
  When we shift by two or more threads, we leave a fil creux behind the duite’s “return”.
