I've just spotted a couple of tremendous videos over on the Spectrum Noir website, using the new watercolour pens! Definitely give these a look then get yours out to colour!
This first one shows you several different techniques for creating some gorgeous backgrounds!
And this one shows you how you can stamp and colour with your pens! See her finished card on the Spectrum Noir blog.
Have a play and show me what you make over on my Facebook page - I'd love to see!
