=Let us examine some of the thin samples.= Here is one which it is almost possible to see through. It is called _voile_ and is thin and gauzy, like veiling. This sample near is called _nun's veiling_. It, also, has an open mesh weave, and is a common wool material. They are both used for dress goods, and are made in solid colors. There are also some printed voiles, but they are usually made of cotton. _Wool voile_ costs from $1.25 to $2 per yard and is woven from 42 to 45 inches wide; while nun's veiling is narrower, 36 inches wide, and slightly less expensive, from 75 cents to $1 per yard. Here are some samples called _etamine_ and _grenadine_. They are similar to the voiles, of open mesh weave, and are used principally for dress goods. _Bunting_ is another open mesh weave. We certainly all know its use. Look at the flag flying on your schoolhouse. Bunting is about 24 inches in width and costs about 35 cents per yard. It is sometimes made from mohair. Here are three samples: one called _brilliantine_; and another, _alpaca_; the third, _mohair_. The brilliantine and mohair do not feel as soft as the wool serges or cashmeres, but rather more wiry. They are made from hair of the Angora goat. They are serviceable, for they both shed dust and wear well. They are used for dresses or dust coats. The Alpaca is made from the hair of the llama, which is bright, strong, and elastic. All of these materials are bright and glossy. Here are their prices and woven widths: Alpaca 36-45 inches 75 cents-$1 per yard Brilliantine 54 inches 75 cents-$2 per yard Mohair 40-54 inches 50 cents-$2 per yard =There are still some common wool materials we have not mentioned.= Yes, _blankets_. They are made of cotton as well as of wool, or of a mixture of the two. They cost from $7 to $30 per pair if all wool. The combination of cotton and wool can be had for less. _Carpets_ are also made from wool yarn. They are woven so that the yarn stands up in loops, and then these loops are cut as in velvet carpet. In Brussels and ingrain carpets the loops are not cut. Suppose you plan to arrange your sample books with three columns of materials made from wool. You may have four or five columns if you prefer to put the mohairs, alpacas, and brilliantines by themselves, and the blankets and carpets in a separate column. That is the way the Pleasant Valley girls arranged theirs. The first will be the heavy materials; then the medium weight, and then the thin ones. It is easy to sort and label them now that you know their names, uses, and widths. Before very long we shall learn the story of how the wool fiber is made into so many different kinds of cloth. It is treated by different processes in manufacture in order to get a smooth close finish or a loose wiry finish. We shall learn how. EXERCISES AND PROBLEMS 1.
