I have recently finished a new piece in spalted beech called Eternal Love. A bit tricky to carve as beech is quite hard to carve and the spalting makes the grain a bit unpredictable However the beautiful grain rally suits and abstract piece like this.
Spalting is caused by fungi growing in the living tree or after it has died and causes unique colouration and patterns in the wood. After carving it was sealed with two coats of Danish oil and finished with bees wax.
Eternal Love is a Mobius strip which is basically a strip which has been formed into a loop after giving one end a half twist. This creates a form which has one continuous side and one continuous edge, an infinite loop. It is a symbol of infinity, eternity and unity where two sides become one intertwined form.
