Use geometric shapes to create interesting packaging solutions.  TABS is a programme available at school that will create a variety of shapes and draw their NETS. The nets are   complete with the necessary 'tabs' to join  2-D surface together to create  fully 3-D shapes

Use 'TABS' for Net - production
