These earrings are made from the reclaimed roof from the Maine statehouse capital building replacement in 2014.
This design has some extra design elements. The subtle fold on the bottom is a technique called fold forming.
***Charles Lewton-Brain invented fold-forming, a completely new way of forming sheet metal quickly into wonderful 3-D shapes and textures, most from single sheets of metal without any soldering. Fold-forming uses sheet material, folds it, works it, then unfolds it.
I use fold forming extensively in my work.
Each piece is cut by hand, sanded, and if I choose to get more creative with the design, a patina is applied.
