The evening star. Alvaro is a natural wool blend with a sophisticated twist that injects textile highlights into upholstery. The metallic yarns of its four colour versions span the arc from the golden reflections of the rising sun in bone and graphite to the cooler silver accents of the setting moon in natural and silver. Their fine shimmer sparkles in the thick wool yarn, giving the soft yet highly durable fabric (with 70,000 Martindale rubs) its elegant touch.
