Tree Hundred - Grow Your Own (GYO)

by Lena Yokoyama (ISSHOO Collective)

Grow Your Own (GYO) is part of a campaign called Tree Hundred which is a collaborative print project between illustrator Ollie Weaver and ISSHOO Collective (Rory Wynn and Lena Yokoyama) - 3 illustrators aiming to visually promote positive climate action. We believe that illustration can be a tool to make subjects more attractive and therefore engaging while providing bitesize reminders to take care of our lovely planet.

20% of all profits will be donated to Greenpeace. Your support matters!

For all our shirts we chose a 100% combed organic cotton garment which is ethically made and manufactured using sustainable energy with an ethical score of 5 stars.

The artists behind the campaign:

We’re Ollie Weaver, Rory Wynn and Lena Yokoyama. We’re 3 illustrators who graduated from Camberwell College of Arts together in 2020 and now work, eat and draw together in a shared studio in South London.
