About Marley's Monsters

Marley's Monsters is a woman- and family-owned small business founded in 2013 in Eugene, Oregon, by Sarah Dooley, who started sewing reusable cloth goods on Etsy during maternity leave and named the brand for her daughter. It makes washable replacements for disposables, such as UNpaper Towels, cloth wipes, unsponges, and food wraps, made in the United States.

The stated mission is sustainable living one simple swap at a time, and the brand ships plastic-free. It leans on made-in-USA reusable design rather than formal certifications, and its durable cloth goods sit at a premium price compared with the disposables they replace.
