Fig. CVII.

To give a clearer understanding of the foregoing, a sectional cut of an Ingrain carpet fabric is given in [Fig. CVII.]

Suppose the filling-threads for the figure to be:

Red, indicated by heavy shaded circles; picks 2, 6, 10, 14, 18, 22, 26, 30.
Black, indicated by full black circles; picks 4, 8, 12, 16, 20, 24, 28, 32.

And the filling-threads for the ground to be:

White, indicated by empty circles; picks 1, 5, 9, 13, 17, 21, 25, 29.
Olive, indicated by light shaded circles; picks 3, 7, 11, 15, 19, 23, 27, 31.

A careful examination of the drawing shows that the white threads mate with the red, and the black threads with the olive, so that when one of these colors shows upon the face the mating color will show upon the back, and vice versa.
