I started with one of the lovely Invoke Funky House images stamped onto a background I'd previously created using Adirondack Colour Wash Sprays.
I love Tina's idea of clear embossing over the top of your work - it really accentuates the colours.
Here are 3 similar backgrounds I made at the same time. I just used 2 colours; Lettuce and Stream. Hope to buy some more soon though! Thanks for the inspiration Karen.
