Here are a few cards I did with my Watercolour Wonder Crayons and Aqua Painters. I embossed on watercolour paper with black embossing powder first, then coloured. The Stampin' Up! watercolour paper can hold quite a bit of water, and I've never had it pill on me. So, even if I don't like something, I can get it quite wet and mop the colour off and start again.
