I have used Verday Paints on these two ceramic cups. On the Bluey one I used mainly copper and brass which go blue, and on the rusty one I have used mainly brass and Iron which give this lovely rusty effect.
You can achieve lot of interesting results with these paints by using the different colours on the same piece. If you don't like the colour just add more layers, but wait until the first one is dry or it will not give you the lovely effect you want.
I thought these cups fitted in well with out Olympic Circle theme this month, for full detail is this months challenge and details of how to enter see the challenge blog post HERE.
