Plate 8. Hamadan Rug

These distinctions in the weft relate to the material of which it is made, its colour, the size of the diameter, the way in which it is spun, to its loose or compressed condition between separate rows of knots, as well as to the number of times it crosses the warp between them, and to whether it is inserted with much or little slack. Most rugs are woven with woollen weft of a natural colour, but occasionally it has a reddish brown, a blue, or a yellow tint. When cotton, jute, or hemp are used, they are almost invariably of natural colour; only in a very few pieces, as some of the Kulahs, are both wool and jute ever used in the same piece. The weft of some classes, as Bokharas, Sarouks, and Bergamos, is of a very small diameter, and of others, as the Hamadans and Kurdistans, it is of relatively large diameter. In some classes, as the Karajes and Genghas, the weft is tightly spun like twine; while in the Beluchistans, Mosuls, and Kurdistans it is loosely spun, so that the projecting fibres of wool give a rough appearance to its surface.

Also the weavers of some districts invariably compress very firmly the yarn of weft between every two rows of knots, while other weavers compress it only to a slight degree; as, for instance, in the Afghan, Tabriz, and Kirman the rows of knots are pressed down so firmly that the weft is almost concealed at the back and the transverse threads of warp are entirely covered; whilst, on the other hand, in the Karabagh or Kazak between every two rows of knots the weft and part of the transverse threads of warp are exposed to view. According as the rows of knots are pressed down upon the threads of weft or not, one of the two halves of each separate knot, as shown at the back, may extend slightly or very much beyond the other in the direction of the length of the rug, or each of them may lie in a straight line at right angles to the warp. Comparing Kazak, Kutais, and Tiflis rugs, for example, it will be noticed that as a rule the line thus formed in Tiflis rugs is nearly an even, clear cut line at right angles to the warp, that in the Kutais part of one knot extends beyond the other, while in Kazaks this unevenness is even more conspicuous. Or again, if typical Shirvans, Kabistans, and Daghestans be compared, it will be noticed that in Shirvans the half-knots, or parts of the knot encircling the two adjacent threads of warp, are often inclined at an angle of at least thirty degrees to the line of weft so as to present a serrated appearance, but that the alignment formed by knots of Daghestans is nearly even, and that of Kabistans is intermediate. To be sure, there are exceptions to this rule, but these features are remarkably constant.

The number of times that a thread of weft is inserted between two rows of knots varies with the practice of different localities, but is almost constant in each locality. Weavers of Sehna rugs insert only a single thread of weft between every two rows of knots, which winds in front of and behind alternate threads of warp, with the result that the back of these rugs have a checkered or quincunx appearance, caused by minute portions of exposed warp and weft crossing each other at right angles. In Hamadans a much heavier thread of weft passes only once before and behind alternate threads of warp, so that the appearance of the weave is very similar to that of Sehnas.[9] In almost all other rugs the weft crosses twice, that is, across and back once, between every two rows of knots so as to completely encircle each thread of warp. The weave of a few rugs, as some Anatolians, shows the weft crossing three times, that is, twice in one direction and once in the opposite direction. In the Genghas, Tcherkess, Bergamos, and in many rugs over one hundred and fifty years old, the threads of weft frequently cross many times; and it is not unusual for the number to vary in different parts of the same rug. In Plate [B], Figs. 15, 16, and 17 (Page 49), is illustrated the appearance of the back of rugs in which a thread of weft crosses once, twice, and three times between two adjacent rows of knots. There are likewise rugs in which the number varies with methodical regularity; for instance, in Khorassans it is usual to find an extra thread of weft inserted at intervals of every few rows of knots; in many Herats the threads of weft cross twice between several successive rows of knots, then three times between the following several rows, and so continue to alternate; and in some of the Kulahs a thread of woollen weft that crosses twice alternates with a single coarser thread of jute.

As the shuttle passes back and forth, the thread of weft may be allowed considerable slack, so that when it is pressed down by the comb it will fit about the sides of the warp; or it may be drawn tightly across, so that it has a tendency to displace the threads of warp. If, for instance, a Hamadan and one of the Feraghans which, unlike the majority of them, has only one thread of weft crossing between the rows of knots, be examined, it will be seen that in the Hamadan the weft crosses with hardly any slack, so that the warp stands out clearly and well defined at the back; but that in the Feraghan the weft crosses with much slack, so that it folds about the warp, which accordingly seems slightly imbedded in it at the back. In some rugs the weft is passed across once with very slight slack, and as it recrosses it is allowed much slack. These features of the weave, which are followed with remarkable constancy in the same class, can be observed to advantage in a fragment of a rug cut transversely to the direction of the warp. If, for instance, the weft which crosses and recrosses between the rows of knots be carefully removed so as not to disturb its mould, it will be noticed in the case of many rugs that each thread of yarn has a similar shape of moderately deep undulations, which show how it conformed to the warp and indicate how slack it was when inserted. In the case of a few rugs, as the Luristans, each thread will likewise have similar undulations, but they will be very prominent. If, on the other hand, the weft be removed from some classes, as the Tabriz, Sarouk, and Kashan, one of the two threads will be almost straight or have slight undulations, while the other thread will have deep undulations. The weft of the Herez, Herats, old Khorassans, and Koniehs have the same peculiarities, excepting that the thread with very slight undulations is of three or four ply, while the other is of a single ply.

The only instruments employed in weaving are the knife, comb, and scissors. The first is used, after each row of knots has been tied, to cut the ends of yarn to nearly the proper length; the second, to press firmly each row of knots; and the last, to trim the nap with care, so that the finished product may present an even and compact appearance.

Finish of Sides.—As the sides are constantly exposed to wear weavers of different districts strengthen them in different ways, which may be designated as Weft Overcasting, Double Overcasting, Weft Selvage, Double Selvage, and Added Selvage. Each of these terms, though not euphonious, suggests the method employed. In Weft Overcasting (Plate [B], Fig. 11, Page 49) the thread of weft, after encircling the threads of warp to which the knots are tied, is wound about a much heavier cord that is strung at the side of the rug for a space equal to the thickness of the knots. It then partly encircles the threads of warp between the next two rows of knots as it passes to the other side, when it is wound about the heavy cord there. As this process continues, the cords at the sides are completely overcast with the thread of weft. When the sides have a Double Overcasting (Plate [B], Fig. 12), heavy yarn is wound about the cord that has previously been encircled by the weft. Frequently several threads of yarn take the place of a single heavy cord. Weft Selvage (Plate [B], Fig. 13) is made by placing two or more heavy cords instead of a single one at the side of the warp, and encircling them by the weft in figure-eight fashion. As they extend beyond the rows of knots they form a plain flat selvage. The Double Selvage (Plate [B], Fig. 14) is used among nomadic tribes such as the Beluches and Afghans, whose rugs receive an unusual amount of hard wear, so that an extra selvage is necessary. In adding this extra selvage the threads of weft are carried about the heavy cords, as in weft selvage, and then the extra yarn is wound over it in figure-eight fashion so as again to encircle the heavy cords. In Added Selvage the heavy cords are not encircled by the weft, but are attached to the side of the rug by the extra yarn that winds about them figure-eight fashion, and also encircles two or more adjoining threads of warp. Sometimes also the selvage is “Mixed,” or made by the weft encircling only one or two of the heavy cords, and then an extra yarn is wound about these and the remaining cord or cords. Moreover, the Double Overcasting and Double Selvage may be “attached” more firmly to the sides of the rug by the yarn passing in figure-eight fashion about the adjacent thread or threads of warp between the two rows of knots. When a Double Overcasting is thus “attached,” it is somewhat similar to a two-cord Double Selvage.

These are the principal methods of finishing the sides, though they are sometimes modified by tribal customs. Simple as they seem, skill is required in both overcasting and making the selvage; for if carelessly done the sides are frequently made to curl. This is occasionally found to be the defect of old rugs, the worn sides of which have been recently overcast by inexperienced weavers. When such is the case, removing the stitches and overcasting with more care will remove the defect.
