On a piece of cardstock, I made a second design with Joggles / Keren Tamir Stencil – Triangle Grid ( JGG ). This bigger stencil gives you the opportunity to make bigger designs in one take.
The leftover foil piece is added to a second card this will give you the positive and negative of the stencil pattern.
With another layer on top, you can turn this in a pretty double-layered foil background.
