Step 1
Cut a strip of cardboard about 3cm wide and tape it together to make a circle. You can use your head to measure it if you'd like to be able to wear the helmet. Make sure it's a little loose at first to allow for the sections you will stick inside it.
Step 2
Draw a section the size of a face on the cardboard. This will be the front section of the helmet so make it's wide enough to fit around the front of the band.
Step 3
Draw some eyes, a nose and a mouth. These will show you where to stick eyebrows and a moustache later!
Step 4
Cut out the eyes and bend the face section so that it fits around your face. You can use a rolling pin or another heavy object to hold the shape.
Step 5
Use sticky tape to attach the face section and band together.
Step 6
Using scissors or a craft knife, cut the sides and bottom of the nose section. Make sure not to cut it off completely, you want it to stick out. Ask an adult to help you with the scissors or craft knife.
Step 7
Draw equal-sized triangles on a piece of rectangular cardboard and cut them out.
Step 8
Attach the triangular pieces to the band using sticky tape. You can add another piece of cardboard from the front to the back to make it easier to attach them if you like.
Step 9
(Additional image for step 8).
Step 10
Make sure all the pieces connect at the top. You can also add another piece of cardboard here to keep them all together.
Step 11
Next, you need to attach a neck guard to the back of your helmet. Cut out some panels, around the same length as your face section and attach it to the inside of the band using sticky tape. If you'd like to be able to wear the helmet you might want to attach them to the outside in order to make sure it is not too small afterwards.
Step 12
Use some of the leftover pieces of cardboard to make decorations for your helmet. You can add eyebrows and a moustache like the Royal Armouries reconstruction.
Step 13
Paint the main sections silver, leaving the decoration plain.
Step 14
Now paint the decorative sections gold or any other colour you think would look good.
