My esteemed listmates, Odd but necessary question, por favor? I run a Sewing Group and a Quilting Class at our library along with our Makerspace and 3D printing. We have this rickety cheap aluminum framed rolling car which stores sewing -type supplies. It wobbles all over and lists like the Titanic. I've read mixed reviews re: rolling carts on Amazon and Googled results display manufacturer created "Best Carts" sites. Have you found a truly sturdy rolling cart? Thank you kindly, Charles.
