1. Cut each diamond into quarters through the centre segmenting the central diamond. Using two rulers helps wih making an even division.
2. In two quarters the centre diamond will have an obtuse angle on the outer edge and in two an acute, sharp angle.
3. Arrange with the six sharp angles meeting in the centre and the six others in the spaces created on the outer edge.
|Each diamond is quartered through the sides.|
|The top two have acute angles the bottom two, obtuse.|
|Rearrange as shown|
