An elusive and mysterious group called the Postcard Underground has been mailing us some lovely postcards over the past few weeks. Some quotes from their postcards: "You're doing exactly what mycelium does: all these little living tendrils connecting and morphing something new and life-giving!" "shroom the world!" "Hearing about your undertaking lifts my heart. Loud clapping form here!" "We thank you. The Earth thanks you! He Thanks you too --> [picture of a polar bear]." "With creativity like yours there is a chance we can rid the planet from the onslaught of Styrofoam. Your work gives me hope for a greener and cleaner future! Thanks!"Wow, thanks to all those kind souls who have written to us! It's incredibly motivating to feel this positive energy coming in from all over the world!
