Diagram for Fig. 76.
In setting figures in a sketch the appearance of “streaks” must be avoided. To do this it will be found advantageous to sketch more than one repeat of the pattern; if possible, sketch two each way, that the streaking, if any, may show itself in the sketch, and be corrected there. Nearly all the patterns seen in fabrics which show streaks can be traced to designers who prepare their designs without sketches; for if a sketch had been made, the streaking of the fabric might have been foreseen had the designer exercised proper care in the examination and perfecting of his sketch. Figures taken from plants, or from life, can be set in the same manner as explained for Figs. [69] to [76]. For example, [Fig. 77], the figure for design. [Fig. XXXIV.], p. 32, the latter being set after the method illustrated by [Fig. 70.]
Fig. 77.
Figs. [XXV.], [XXVI.], [XXXIII.], [XXXVIII.], [XLI]., [XLIV.], [XLV.],[ XLVII.], [XLVIII.], [LI.], [LV.], [LVII.], [LXI.], etc., all show sketches for fabrics executed on one or the other methods of construction just explained.
Size of Sketch Required.
This is regulated by the number of harness-cords in one repeat or division, the method of tie-up employed, and the texture of the finished fabric. For example: Take 400 harness-cords for one division. Texture of the fabric when finished 100/90. Tie-up employed, straight-through. Required: The size of one repeat for the sketch.
Answer: 400 ÷ 100 = 4 inches. The figures may be arranged in this sketch to repeat one, two, three, four, or more times in the 4 inches thus available.
