Harlequin Indoor Outdoor Weaves Aelius Mineral/Ivory Fabric . Aelius has a speckled texture, playing with tones in its weaves for a charming look. It is flecked in three colourways, all anchored by an Ivory thread that is made from recycled fibres specially developed to create sustainable furnishing fabrics. The finished weave is coated in a Carbon Zero (C0) finish, a water and stain resistant finish that provides a high level of stain and water repellency.
