You may already use cloth bags when you go shopping, but do all your friends?
Check out the Hemp Earth Art shop where you can find one here that resonates with you to get help get friends and family members interested in the reasoning behind your using them.
Or, do you know someone with a birthday coming up?
You could buy a reusable cloth bag here that you place their birthday gift inside.
This has two sustainable advantages! There is less waste after the party, and that person now has a good start and reason to be using a reusable bag when they go shopping.
Each time they use it, it will replace at least one plastic bag that their purchases would have been placed in.
Happy Birthday to a Friend of the Earth!
