I didn't know how much work this would be.
Acquiring the sheeting was a story in itself. The man at the sheet metal store told me that yes, they had it, but "that stuff is like gold - really expensive." Furthermore, when informed of my backsplash intentions, he told me I would regret it and it would gather dust and I really should reconsider. Since the office at this place had dust piles and spiderwebs in all the corners, it seemed unlikely that he could be a compulsive duster. Hmm... I assured him that I was determined to buy copper, so he rang up my $47 worth of "just like gold". As I handed over the cash he said that business is really slow and and he might as well just go home. I left Eeyore in his dusty office and escaped with my copper.
Next came the pounding. I had naively assembled a variety of objects to pound with in hopes of creating interesting patterns. None made so much as a dent except the balpeen hammer. Okey doke - a simple hammer job should look kinda rustic and catch the light nicely.
Much, much work. Leaving the plastic coating on to avoid scratches, I wailed away at the two sheets, frequently flipping them to beat on the other side to keep them relatively flat. A sheepskin on top of a solid wood chair made a nice solid work surface with just enough give. If you try this, I recommend frequent rest periods. Despite the stiff shoulder, the effect is worth it. I'll deliver the panels for installation on Sunday.
