You can emboss all kinds of patterns and textures into fiber paste. You can wait until the paste has partially set up and then emboss into it, or you can spread it over a plastic texture plate and let it dry. Because the fiber paste dries against a slick surface, it will look slick on the embossed side.
STEP ONE: Apply fiber paste on an embossing or texture plate and let it dry.
STEP TWO: When dry, peel off. Any color residue on the plate transfers to the dried paste.
STEP THREE: Cut up and use the embossed fiber paste as a collage element in your art.
