My most favorite technique would be two-fold. I love to make things look old ~ like they have had this wonderful history. Like this piece was found in an attic somewhere and you can just imagine the story behind. I can only achieve this by using stamps and/ or molds - they aid me in adding just the right touch. A crack here or a date there. Maybe a partial image. I put this all together and give it an antiquing or patina rub using acrylics and the effect to me is magical.
