Sounds like a fun mess and a great way to keep the city green. Banknotes are paper, so you’d need a biodegradable matrix to hold the soil and seed. I could mix some compostable polymer with the old bills and test a tiny planter. The glue will have to be plant‑friendly too, or it’ll just decompose without holding anything. Let’s prototype a few and see how the notes behave in the soil—if it works, we’ll have a quirky little garden mosaic right under the traffic lights.

Will do. I’ll keep the watermarks in place, maybe tape a little flag so it won’t blow away. Expect a handful of failed rolls before I get one that actually holds soil and a seed. I’ll send you a photo of the first batch tomorrow. Stay tuned for the garden of folded money.

Will keep the watermarks as my little guardians, they’re the pulse of the paper. I’ll set up a test bed tonight and send a pic as soon as something actually holds a seed—hope it’s both elegant and a bit chaotic. Keep an eye out!
