Harvest Black Gray is a rug from Kasthall that belongs to the Harvest series. This collection is characterized by being made from leftover yarn in pure wool. Each spool of yarn continuously shifts in shade, resulting in each rug having a unique and distinctive aesthetic. As it is leftover yarn that is used to weave the rugs, this means that no spool is identical to another, and this creates beautiful natural color variations on each rug. Using leftover yarn in manufacturing also makes it an environmentally friendly and sustainable option for those who care about sustainability and reuse.
