ManiacQuilter2 - Hi! Actually, Walmart doesn't sell anything similar to these carts. They have rolling laundry carts and things like that, but nothing with the high sides so stuff doesn't fall out.
I forgot to mention that the Ikea Raskog cart also comes in beige or dark gray (in addition to the pretty turquoise). Just in case the blue doesn't match your sewing room décor.
Here's a link to Ikea:

And here's the Target one (this is the gray, it also comes in white):
