Apply a splodge of Antiqued Bronze and Tarnished Brass Distress Paint to your craft sheet.
Mist with water and drag your tag through it.
Now mist your tag with water and let the paint run where you want it to.
Dry it with a craft heat gun.
Take Vintage Photo Distress Ink and blend it all over your tag with a blending tool.
Mist the tag all over with a fine mist of water and gently pat with kitchen towel. The tag should just feel slightly damp.
Now go over it with more Vintage Photo Distress Ink using your blending tool and you will notice that some areas of the Distress Paint act as a resist while other areas absorb the ink.
I really like the effect :)
