Maree Clarke made her first kangaroo tooth necklace with Len Tregonning and Rocky Tregonning in 2008, they revived a cultural tradition that has not been practised in over one hundred years. To make a kangaroo tooth necklace Clarke begins by collecting the teeth from dead kangaroos on the sides of roads. The skull are crushed, the teeth removed and soaked in water for three weeks. For a sixty eight tooth necklace, Clarke needs over thirty four kangaroos, as only the two font teeth can be used. In addition, Clarke along with members of her family collect ochre and wattle resin to paint the leather, and use emu oil to soften up the ochre painted leather when it becomes too stiff. Clarke was inspired to revive this tradition when she viewed the historical nineteenth-century examples of the kangaroo necklaces in the collection of the Museum of Victoria.
