Yesterday my husband installed a new mailbox post as our old one had long outlived its time. I bought a copper fence post top for it but realized it had a sealer on it so the copper would never become a wonderful turquoise patina. I realized that I could use my alcohol inks on it and get a fun look which is exactly what I did. I figured that if it didn't work, I could spray paint it. Success! I'm happy and all the neighbors checked it out so I hope they are happy too.
