Cut a piece of cardboard 6cm x 63cm. You may need to join 2 pieces of card if you are using cereal boxes. This is large enough for an adult size helmet. This is the main band around the base of the helmet.
Cut 2 strips of cardboard 3cm x 30cm. These are the cross pieces on the top of the helmet.
Cut out the template for the front of the helmet. Draw round it onto your cardboard and cut out the shape.
If you are using plain cardboard paint all the pieces silver.
Draw or paint any patterns you want on the flat pieces.
If you are using silver card you can draw patterns with the wrong end of a paint brush.
Wrap the strip off card around your head where you want the helmet to sit. It should cover the top of your ears. Mark where the card overlaps. Trim off the excess, but leave an overlap of about 2cm. Glue or staple the ends together.
Attach the cross pieces to the crown of the helmet using glue or staples. Attach one side of the first piece and try it on your head before attaching the other side. It should be just above the top of your head. Attach the second cross piece so that it just rests on the first in the centre.
Using the template, cut 4 shapes from crepe paper (or fabric) to fill in the top of the helmet. Glue or tape them into place from the inside. You may need to trim them slightly to fit if you are making a smaller helmet.
Attach the front of the helmet, lining up the nose with one of the cross pieces.
Glue on any other details as desired.
Cut a piece of net fabric approximately 25cm x 50cm. Tape inside helmet along back edge.
