As prices and building costs keep rising, the “do-it-yourself” (DIY) trend (趋势) in the U.S. continues to grow.

“We needed furniture(家具) for our living room.” Says John Ross, “and we just didn’t have enough money to afford it. So we decided to try making a few tables and chairs.” John got married six months ago, and like many young people these days, they are struggling to make a home at a time when the cost of living is very high. The Rosses took a 2-week course for $ 280 at a night school. Now they build all their furniture and make repairs around the house.

Jim Hatfield has three boys and his wife died. He has a full-time job at home as well as in a shoe making factory. Last month, he received a car repair bill for $ 420. “I was deeply upset about it. Now I’ve finished a car repair course, I should be able to fix the car by myself.”

John and Jim are not unusual people. Most families in the country are doing everything they can to save money so they can fight the high cost of living. If you want to become a “do-it-yourself”, you can go to DIY classes. And for those who don’t have time to take a course, there are books that tell you how you can do things yourself.
