Recently I was in Nike Town, looking to buy a pair of running shoes. An assistant said, "The upper of the Nike Flyknit Trainer+ is the same weight as two sheets of A4". Walking out of the shop, I realised an ad had dropped in my lap. 

 

I made the ad out of two glossy sheets of A4 and some laces. I then went back to Nike Town and showed it to an assistant. He called the manager down. "Can we show it to our brand team?" she said. On this back of this, they invited me to do more work with them.
