For this design I was going for a sort of weathered copper effect, but I also wanted the finish to be matte.
I started by painting all my nails in 2 coats of a metallic teal/turquoise shade.
Once this was dry I used a bronze coloured polish and a flat brush. I brushed off any excess onto some tin foil and then used the brush to dry brush an effect over the top of each nail.
I repeated this again to try and build up the effect a bit more so that there was more prominent areas of the bronze showing through.
I then finished off the design with 2 coats of a matte top coat.
