Nice piece in Fast Company by Zachary Petit:

One critical moment came in February 2010, when J. Crew featured Field Notes in its catalog, alongside the retailer’s other “personal favorites from our design heroes.” There was a Timex watch, Ray-Bans, Sperry shoes — “and out of fucking nowhere, Field Notes,” Coudal says. “And when that happened, a lot changed for us.”

Coudal says it gave the brand instant credibility — after all, if it was good enough for J. Crew, it was good enough for your store. In time, friends began sending him screenshots of Field Notes in TV shows; he and Draplin would see people jotting notes in them in bars and elsewhere; on the design web, they became an obsession. By 2014, there was even a subreddit dedicated to them titled “FieldNuts.”
