I miss that zip-zip sound corduroy pants used to make when I was a kid. Cords seem to have lost something from the ribbed pants of my stripey-shirted, yes-avacado-is-a-colour-and-it-goes-great-with-pumpkin, 70’s childhood. So, I’ve been wondering as I walk around, my pants more of a stuttered whisper than that zip-zip I used to love, what’s changed?
