To be a good judge of a carpet you need to be quite an expert. Many things have to be taken into consideration. First the dyes, as we have already seen; then the number of stitches to the inch must be counted, and it is said that a good carpet contains about 10,000 stitches to the square foot, while some of the better ones have as many as 40,000. Another point to notice is to see whether both ends are the same width. This is done by doubling the carpet: if the ends do not coincide it is not a well-made carpet. Then, again, it should lie perfectly flat on the floor, otherwise it will crease in a very short time, and be worthless. My husband had a beautiful Kerman carpet given to him once: it was valued at £20, and, but for the fact that it does not lie flat on the floor, would be worth a good deal more. As it is, we have to keep it hanging on the wall, where it cannot get "rucked" or creased.
Prices vary, of course, according to the size and make of the carpets. Very fair ones, the size of an ordinary hearthrug, can be had from £2, 10s. to £8 or £10. Silk ones cost a great deal more, but are worth the money. A small silk rug can be bought for £50, but they can be obtained any price up to £500 or £1000. A mixture of wool and silk is now made to suit the European market, but is not so durable as the pure silk ones. It is generally acknowledged that the Kurdistan carpets are the best: they are the most expensive, being about £3 the square yard. The chief attraction of these lies in the fact that they are alike on both sides, and are very smooth and fine. Next to these come those made at Kerman, the design being quite different to those of Kurdistan. In the Kerman carpets it is not at all uncommon to find figures of men and animals, sometimes almost life size. Whilst in Kerman we visited one or two of the carpet manufactories, and were very much interested in watching the process.
All carpets are, of course, made without machinery of any kind. The warp is stretched on a loom, which is merely a frame. The woof consists of short threads woven and knotted by hand without the aid of a shuttle. When a row is finished it is pressed tightly to the rest of the web by means of a comb inserted into the warp. The "pile" is regulated by the amount clipped off. For a velvet pile the woof is clipped very close, till a perfectly smooth, even surface is obtained. The weaver does not see the pattern as he works, as he sits with the reverse side of the web towards him. The looms are generally kept in an underground vaulted room, often with water running through the centre. At each loom three or four workers sit, according to the size of the carpet. Sometimes the workers consist of one man and two children, and occasionally the owner uses boys and girls only for the weaving, one man acting as overseer to the children.
