Break up two bars of soap in to small chunks. You can grate the soap but I blended mine in a bean grinder to make it powder like.
Put the soap in to a plastic jug and place in to a pan of boilng water. Leave to cook in the pan for about 20 minutes. The soap will go soft.
Add the olive oil and mix in well. Place back in the pan and leave to cook for another 15 minutes.
Add the orange rind, vanilla oil, cinnamon and mix.
Pour the soap in to a mold and flatten and compact it with your fingers.
Leave to set for about 5 days. The soap will be hard and compact. Remove the soap from its mold and cut in to square slabs.
