All of my guitar straps have been hand-me-downs from my dad. They still smell like his parents' attic but have aged well in the 40 years since he bought them. But there are only two, so I was a bit lost when I found myself with a new guitar and no more straps hidden in damp storage.
I decided the best solution was to stick with what I know and get one in the same pattern as one of the 1970s straps—either Neil Young peace signs or Duane Allman stained glass. I chose the latter, since that's what Chicago strap company has in stock. The company hand-makes all its throwback-patterned and custom-designed straps, all of which are backed by used seatbelts. Even more important than their seatbelt strength is the look: nearly indistinguishable from the real deal, albeit a bit brighter without decades of aging.
