CAS Colours & Sketches Challenge #125: Colours.
I don't have Stampin'up products, so I used my Distress inks as watercolours and I think they're a very close match.
I traced the stencil in the corner of some watercolour paper with a Sharpie and filled the shapes in.
I used some Iridescerent medium from Windsor & Newton to dilute the Distress inks so it has a nice shimmer.
Don't think it shows up well on the photo though.
Simple but fun font greeting from Sizzix.
