The burlap was almost new I wanted it a little darker so I soaked it in coffee and tea. The longer it sat in the coffee the darker it got.
I would love to print on old paper but my printer just rips it up. So the next best thing to do is ruff it up with sand paper. I even sanded a hole to add authenticity. I also used Distress Ink and brushed it with a little water. Now I'm happy with it.
The label says "Our Lady of Abundant Inspiration" I hope this can inspire you to try to age a project of yours.
