I was excited to find these great “Recycled Banner Golden Mean Messenger Bags” DIY instructions a la Freitag bike messenger bags. (Can be made under $5 !!!!!!!!!!!!!). Comfortable, light, tough billboard sign material (waterproof). To view instructions please visit: EEIO Golden Mean messenger bag instructions
In stores, nice bike messenger bags can be $200. Making your own not only saves money but also is good for environment. I just saw a truck driver discard a big piece of truck tarpaulin and now it is lying on the street waiting to be made into bags.
