In order to keep this chart handy, print it off and hang it above your washer. Or, if you’re a renter like me, tape it to your detergent or laundry basket.

Alternate ideas if you’re opposed to wasting a piece of paper:

  • Bookmark this page and keep your iPad with your dryer sheets.
  • Cross-stitch it on your organic cotton socks. ALL FIVE OF THEM.
  • Get a (vegan) tattoo of the symbols. Bonus: Tattooing it on your back, so someone still has to check your tag for you. Bonus bonus: Sassy quip about wrinkles.
