Starting a stamp collection is easy and not very expensive. Before you start, you need to decide what kind of stamps you want to collect. Most people collect stamps that they are interested in: a certain country or an animal, a famous person or even a sport. Whatever you choose, you will find that there is a world of knowledge in stamps: you will learn about people, geography, building, history and culture.

You can collect stamps from letters, ask your friends to let you have their old stamps, or you can buy used stamps. Cut out the stamp carefully when you get a letter with a stamp on it. Leave lots of space around the stamp so that you will not damage it. Put the stamp in water and wait until you can safely remove the stamp. Carefully remove the stamp off the letter. Place the wet stamp between two clean pieces of paper. A stamp can get winkled(褶皱) when it dries, so put some books on top.
