This reminds me of those fun children's toys with the colourful beads that slide about. This one is almost three feet high and holds eight spools. Rather sculptural-looking I think. You could stack spools of seam binding or Washi tape on all those spindles.
Yes, they are still dusty. I would be most surprised if we aren't all familiar with the stuff. It's everywhere!
How would you put them to use?
