Repurposed Road Sign Canvas for Refugee Tents

At the moment, there are people re-using the spent billboard signs that are made of canvas instead of the old-school paint/wallpaper style billboards. They use it to make recycled messenger bags and chic purses. I like that, but I like this better: Keep the canvas in one big piece and send it to refugee camps with simple instructions for making it into a tent. It's waterproof, flexible, colorful, and recycled. The refugee crisis we currently see is nothing compared to the possible surge in the future due to natural disasters and a possible outbreak of mid-east warfare. Gimme (Give them) Shelter!
