I was given a challenge by Graph'it to only use these 9 new colours on a card. I immediately thought of using my Home Sweet Home stamp set. It wasn't too hard. To create darker shades I would just keep layering and build up the colour and to lighten a colour I used the blender marker 0000.
I did use the colour Glass on the window (so a cheated just a smidge). I love Graph'it markers, it's the only marker I use to colour my stamped images.
