Below is an image of the placemat. We use it to show how to turn the cube, which face to turn and in what direction to turn that face...
Hold your cube in front of the placemat or put it on top of the placemat if you have saved the image and printed a physical copy. The cube must remain stationary in relation to the placemat while you are trying to solve it...
Each triangular section of the placemat relates to the face of the cube that it is pointing at in the picture. A blue triangle section means you must turn that face in an anticlocwise direction. Red means turn that face in the clockwise direction.
