Applying Decoupage glue in multiple thin coats and allowing it to dry between coats will help you to ensure the finished surface is smooth and completely glued down.

Step 3. Smoothen The Finished Decoupage Surface

When you have used Decoupage materials such as paper, fabric, or napkins. It’s a good idea to use a brayer or roller to lightly flatten and smooth out the surface.
