I really don't like to throw anything away, I recycle some but for things that can't be recycled I try to come up with something to make from it.
I love these gift bags, they are fast to make and have no waste. Try one out when you need a gift bag in a hurry and can't get to the store in time.
This bag saves energy in at least two ways. It saves you not having to drive to the store for a gift bag and it saves energy because then there is at least one less bag being made that would have been bought. If this catches on an many people reuse their chip bags for gift bags, that is saving a lot of energy.
