Have you tried any of the “rust effects” products available yet? Well I have been playing with the Creative Expressions Cosmic Shimmer Paint effects sets – rust and patina. I love them! Think you need both as the combinations are so effective. Each set brings you 4 paints in shades from dark to light and a metallic finish paint. When you apply the paints, start with the darkest first, using a brush and or sponge – I used brush then stippled with sponge. It is as if by magic that little grains appear….sand?… you do not see them in the bottles of paint but as soon as applied you do! I have tried on glass bottles and also wood/mdf and greyboard – all great!. These sets are in stock at £11.50 as an introductory offer…brilliant! Also in stock are the sets of Kaliedoscope paints, shades of pink, or lilac, orange, or jade, and work in a very similar way.
