So I've been playing with my new Bombshell stamps and experimenting with different ways of colouring them in. First of all I tried my usual watercolour pencils which worked well for shading, especially if I layered the colours to get more depth of colour.
Next I tried 'The Blonde One's' Pro Markers which are artist quality felt pens. These gave a much more cartoon like quality which suits the image. They are also easy to layer to give shading.
