For a challenge I needed to craft up something that was eye-searingly brightly colored and that would take 6-8 weeks of work. And I figured that along with being ridiculously bright it might as well be a bit over the top as well. And I'm pretty sure that a double rainbow neon color scarf with fringe that is over 9 feet in length fit the bill nicely. I also edged it in black and separated the two sides with black which after sampling I think made the colors pop a lot more.
I'm almost afraid to see this outside in the bright sunlight. But on the bright side (pun intended) if we ever happen to have a snow apocalypse here, I think this would be easy to spot.
