Silver Threads is a Plain City, Ohio workroom with decades of experience creating tailored interior treatments for hospitality and commercial spaces. Its people bring unusually deep practical knowledge to the work, including a vice president who started handling fabric bolts in his uncle’s window-treatment business at age 10 and a design consultant who has been with the company for more than 30 years. The team works with architects, designers, and procurement firms on projects such as the Ohio Theatre and World Equestrian Center.
