2. Fray some of the threads of the cloth you wish to buy. Is it possible to break either the warp or woof easily? If so, the silk will split along either warp or filling and will not wear.
3. One should not expect to get bargains in silk. Cheap silk will not wear. It is better to wear some other material. Is the material made of reeled silk or of spun silk? You have learned the difference. Articles made of reeled silk are more expensive.
4. Silk is sometimes adulterated with cotton or artificial silk and sold for all silk. We shall learn some tests in our next lesson so we may discover too.
Miss James talked over all these points with the Pleasant Valley girls and showed them some good and bad materials. The girls decided to be on the lookout for these things. Will you?
EXERCISES AND PROBLEMS
1. Bring to school garments or materials which have not worn well. Try to find out why. Your teacher will help.
2. Write a composition about things to think about in purchasing a new winter suit ready-made. If you must buy from a catalogue, can you judge about the wearing qualities?
