My Counterfeit kit needed some gold spotted paper so I tried a few different techniques.
First, I misted through a scrap of paper to create big dots
It is messier than the original but the joins can be covered by embellishments etc on a layout.
Next, I used Punchinella
Lastly another idea is to use Kindy Glitz through the glue dot holes
Hope these inspire you to try forgeries of your own.
