You can buy a grommet kit in Home Depot or Lowes for under $10 - they're simple to use. That's what I wound up doing, because I couldn't justify paying $60 for 2 towels (much as I love how they look). I found a couple beach towels with a pattern I liked, added grommets in 2 corners each, and use a carbinger to hook them behind my head rests. I only use mine when I'm grungy & don't want to mess up my seats (or when I'm parked with my top off & I want to keep my seats cooler and/or free of bird crap). They're not as cool looking as the jeep towels, but they get the job done.
