Using acrylic gloss medium and about one tablespoon of glitter I mixed up some glitter paint.
The example on the left is the glitter paint on a sheet of plastic. On the right I spread it on heavy weight paper.
Spreading the mixture thin with a card.
When completely dry I was able to peel off from the plastic. Making a flexible film.
This technique could have many versatile applications. Including custom glitter letters!
The paint is also pretty over decorative paper as an accent layer.
