Nice and Shiny made this vest from refashioning a thrifted 80´s biker jacket. If you´re working with a leather jacket, remember that after cutting the sleeves instead of sewing the sleeve openings you can just fold 1cm / 1/4 inch of the edge and glue them with leather/texitile glue. The lining is places between the folded edge. Textile glue also works on denim and thicker canvas and wool fabrics. Eazy beazy!
