I used two different polka dot embossing folders for the background. The penal with small polka dots was trimmed down to be just a little bigger than the panel with the coloured image. They are put together on top of each other in an angle to make the card more interesting.
I also used Wink of Stella to add shimmers to the polka dots on the cup and the big polka dots on the background. Unfortunately, the shimmers were very hard to capture with my camera!
