This is a Thorny Sea Star – we found washed up on a beach dried and bleached . We take a mould – very carefully, it is always a bit of a heart stopping moment in case any part snaps or breaks – we only have one of each shell. if that all works we can then pour the wax into the mould and out comes the 1st stage of the whole process. The next stage is refining the wax replica until it is as near as perfect as we can make it.
