Always on the hunt for something to turn the sewing awl on, I diced a safety vest and tried replicating my Aardvark safety triangle.

Nasty. This is why I don’t usually document my “first tries” (HB-01?), but the progression is interesting:

The later examples use reflective trim that radiates under flash photography and hopefully car headlights.

On Senator Buff, it also obscures the rear reflector, genius!
