I love the WOW embossing powders..they come in all sorts of colours..but I do stamping with coloured ink and then using clear embossing powder over them to get my colours..although..like you I have a selection of others in a little case that I think came free with a magazine once. I bought a couple of coloured ones at the Make it show a few weeks back though.
Great card Ellie..like the way you spritzed the peacock. It deserved some special treatmeant because they are such pretty birds.
