A few years ago I found a marble top that was junked and thrown away. It was forgotten in my attic for many years.
In 2019 a family friend was throwing away an old sewing machine that must have been used in New Haven, CT when manufacturing was prominent.
I re-purposed the industrial sewing machine base and added the marble countertop.
Some would say furniture is art. The Yale Art Gallery and the Metropolitan Museum of Art in NYC have extensive furniture collections.
