I finished my Unicorn. It stands about a metre and a half high. I made the armature from odds and ends including a bit of a lawn mower and the bottom of an old bath tub, the latter providing a stable base. I used tennis balls for the eyes. The covering is granules of silver granite donated by the generous firm of Sureset which makes permeable resin paving. The red of eyes is basalt and the black is copper slag from the same source. The Unicorn will be accompanied by a Lady as in the tapestries in the Cluny Museum in Paris. They will be in the Horseworld Sculture Exhibition at Horseworld horse sanctuary near Bristol which I am curating - on from May 23rd to November 1st.
