Step 3 Cut to shape

open the box top and bottom so that the flaps for the box are open.

Decide which way will be up and which way will be down.

You will be folding the flaps inside the box to add structure and to provide a backing for the spoilers and exhausts. it will also improve the box resilience.

However. You want to make sure the flaps dont overlap when folded inside.

For the bottom of the box.

Cut the Flaps back to half their length and then fold them inside the box and glue them down with the hot glue gun.

For the top of the box.
Choose which will be the front and which will be the rear of the box.

For the top , front . leave that flap alone.
For the top, back cut the flap down to about half its height and again fold it in and glue it.

For the left and right flaps.
Cut then down to about half the height and from the front to back remove the flap completely. Again fold these inside the box then glue them.

Now to create the bonnet of the car.
use a ruler and measure appx 6" of the way down the box front and mark it. ( a )
use the same ruller and measure appx 5" of the way from front to back and mark it (b)
now draw that diagonal line from a to b
Your cutting along the from b to a and leaving the triangle flap.

Draw a line across the front of the box, from b to b and score it ( lightly ) since it will make it easier to fold the bonnet back along your scoring.

Use the triangle flaps to glue back the bonnet inside the car. Take the opportunity to glue the bonnet along its edges.

Thats about it for the glue and cutting frenzy for a while,
