I recently came across these - Ken Oliver's Color Burst powders
Add them to wet paper for a spectacular effect...this was on a canvas paper...
Anyway - I used a snippet of this for an ATC background matted on some blue and red sparkly card.
I added a Bugaboo image Clown Around Hat coloured with Promarkers.
Finally I added three flower gems.
I will add this to Wicked Wednesday ATC Challenge #209 - Circus Act
