Watercolour Thank You is one of the single stamps available in the Annual Catalogue.
I used it for this quick Technique card in my class this week :o)
The paper is from the Back To Black DSP pack. All the paper in this pack is black and white, so it is perfect to colour using the Blendabilities Markers. Because you don't get any lines when colouring, it looks like the paper has been printed with the colours.
