They are stamped in Versamark and then heat embossed with Detail Copper powder. I then covered up the padlock and masked off the end panels to create the clouds with a mask and Ink Dusters.
Next it was the turn of the end panels so I masked off the central section. The keys are stamped in Archival Ink (1st and 2nd generation) and it's distressed with Aged Paper Distress Ink applied with a Clarity stencil brush.
