Do it yourself

An old saying tells us that if you want something done well, you should do it yourself. Today many people seem to take this saying to heart. They do not buy furniture and other things already made. Instead, they prefer to make things themselves. They have become do-it-yourself fans. Nowadays many stores sell parts for making desks, chairs, tables, bookcases, and other things. All you have to do is put the parts together, add some paint or varnish, and you will have made a fine piece of furniture. If you have never tried to do it yourself, you will be surprised how easy it is. You will find a lot of satisfaction in doing it yourself. Besides being economical, it's fun, too.
