Have you tried the faux patina paint from Ten Seconds Studio? This stuff is awesome. A couple coats of paint and you can make anything look old.
Once I painted my box it was time to decorate. While it was drying I dug out some rusty goodness.
The rose was the perfect addition to the box. I knew I wanted it to be the focal point. I had the brass "hers" placard forever. I used alcohol inks to age it and the brad.
I rubbed some black paint and alcohol ink one the key plate. This brass was shinier and just using the alcohol ink wasn't toning it down enough for me.
Watch gears and remnant rubs finish out the decorating.
Now I have a rusty treasure box to add to my jewelry table.
