Rule for Shading With Satin Weaves
Put the ground weave (filling for face) over the entire part of the □ designing paper, which is required to be shaded; afterwards add one, two, three or more horizontal or vertical (connecting) spots to the one spot which forms the foundation or satin filling for face. The heaviness of the shade is regulated by the sketch or the fabric. For example: In an 8-leaf satin the difference between filling for face and warp for face may be made with three or four changes only; or with the entire seven changes.
For shading twill weaves no rule can be given.
Fig. 100 shows the shading of the 5-leaf satin, four changes, each eight threads, giving 4 × 8, or 32 threads for the effect.
Fig. 101 illustrates the 8-leaf satin applied for shading a circle, using in rotation every possible change.
Fig. 102 illustrates the shading of the 10-leaf satin from filling for face 1up 9down, to warp for face 8up 2down, and back again to filling for face.
Fig. 103 represents the 7up 1down eight harness twill, shaded from the filling for face to the warp for face effect; the change occurring every eight picks.
