The Seed Holder Book. This magical little book is crafted from recycled corrugated cardboard and designed to hold pongamia tree seeds and a story about the need to plant trees. It’s a beautiful feeling holding this feathery light book and knowing that you’re holding future trees. It’s a better feeling when the first leaf peeks out at you a few weeks later. Created for Tulika Publishers by Vinod Lal Heera Eshwer.
