Last week was Earth Day so we're mentioning something we saw repurposed. They aren't fasteners but they sort of look like them, right?
The site where I found them says they are old truck springs but they remind me of flat head machine screws. I would love stools like this.
Found this at House Beautiful. Read the whole article because they repurposed SO MANY things in so many ways in this house, it was really surprising and super interesting.
