This layout I designed for Rainbow Splendour for my share this month. I was inspired by the triangles on the pin.
So, I used impasto paste through a Flutterby Designs stencil and then sprayed co-coordinating colours of Colour Blast Colour Spray over the top. The trick is to make sure you dry each colour before adding the next. This limits the amount of colour mixing that happens. It still mixes just not as much.
For some reason this photo looks a little dull but in real life it is pretty cool.
Here are a few close ups too:
