Fold the card in half so that it forms a square.
Repeat the fold but this time top left hand corner down . Again use the bone folder to sharpen the crease.
Open out flat. I have turned the card so that the folds are now on my left. Why didn't I start that way ? Don't ask. Now find the central point on the right hand side and mark.
Using the central point cut back towards the folds to create a point.
Now the tricky bit push the two side folds in over to form the diamond. The left hand section folds forward to make the platform. If you're still with me you're nearly there!
See now you can see where we're going.
