Right outside our shop, where we spend our days working with bolts and nuts, we’ve started something small that means a lot to us. With a bit of help from the folks at KPCA (Keep Pietermaritzburg Clean Association), we’ve put up a ribbon on a tree. It’s our way of nudging ourselves and our neighbors to remember to keep our city, Pietermaritzburg, clean and beautiful.
A ribbon on a tree might seem like a small gesture, but it’s our symbol of hope and action. It’s there to remind anyone who sees it that keeping our city clean starts with us, with every piece of litter we decide not to ignore. It’s about taking pride in where we live and making a positive impact, even in the smallest ways.
We’re firm believers in the idea that if you want to see change, you’ve got to be part of it. This ribbon is our pledge to do just that—to be active participants in making our city a better place, not just for us but for everyone.
We’re inviting other businesses and individuals in Pietermaritzburg to join in. It’s not just about making our city look better (though that’s a big part of it); it’s about what this action represents: care for our community, safety for our streets, and respect for each other. When we come together to clean up our city, we’re really building something bigger—a sense of community and pride that benefits us all.
This ribbon is just a start, but it’s a start we’re proud of. We hope it inspires more of us to take even the smallest steps towards a cleaner, more welcoming Pietermaritzburg. Whether it’s picking up litter, supporting local clean-up efforts, or just spreading the word, every little bit helps.
We’re in this together, and together, we can make a real difference in our city. Let’s show what we can achieve when we all pull in the same direction for the place we call home.
