Putting a jigsaw（拼圖） together is a fun activity and making your own jigsaw is even more fun.You can make a jigsaw from wood，or you can make a simpler jigsaw with cardboard（硬紙板）.Friends and family will love putting together your handmade jigsaws!
   First，choose a picture and prepare your tools.You can print a picture to use as your jigsaw，or draw your own，or even use a card.You also need good cardboard to back your jigsaw.It should be as large as your picture，or you'd better cut it out.You will also need glue，a ruler，a pencil and an eraser.For a cardboard-backed jigsaw，you will need a pair of scissors.
   Next，cover the back of the picture with glue，spread（攤開，使散開） it around，stick the cardboard onto the picture and let the glue dry（干的）.
   Then，use a ruler to mark out and draw a grid pattern（網格圖形）.To make jigsaw pieces，add ball and socket（凹） shapes to the edges of the grid squares so that the pieces will fit into each other when the jigsaw is cut.
   At last，cut out your jigsaw pieces with your scissors.Be careful not to cut yourself.When it is finished，use an eraser to remove（清除） the pencil marks.
