A mixed media collage is made from a variety of different materials.
Most people think of collage as a combination of pictures from different sources, such as magazines, newspapers, or personal photographs, but collage can also include other materials and media. Paint, charcoal, fabric or even organic materials like sticks and leaves are popular additions. When a collage uses a number of different types of materials, some artists define them more precisely as mixed media collage. There are a number of different methods that you can use to create a mixed media masterpiece. Following is a sampling of techniques, but the possibilities are restricted only by a person's creativity.
Pictures and Paint
Creativity Portal artist Chris Dunmire suggests combining the pictures in a collage with paint. Use a brush and your favorite type of paint to work lines, shapes, or even more complex paintings into the pictorial collage. Consider acrylics and watercolor paints; you can include interesting textures if you decide to use a thicker paint. For example, using gouache and a sponge applicator allows you to create peaks and dimpled surface textures.
Including Fabrics and Textiles
On her blog, artist Cindi Lavin provides some captivating ways to use fabric and thread in collages. Pick up colorful satin or silk threads and add embroidery to a collage, or use the thread as a creative way to attach 3D materials, such as buttons, small plastic toys or other objects. Get creative by including textured, flashy fabrics with photographs and pictures. If you have the skill and the time, consider using fabric and thread to quilt shapes and images and paste them to your collage board.
Using Organic Materials
Don't be afraid to experiment with organic materials to give your art an earthy feel. Leaves, flowers, plants and pebbles are some materials you'll want to consider. Try combining natural materials with synthetic ones, such as bright or metallic paints. If you're worried about your art decomposing, use a clear collage sealant, such as Mod Podge, to cover any organic pieces. Using a sealant will keep leaves or other plant-based materials from drying up and flaking off the collage surface, while adding an attractive luster to your work.
Using Metal in Collage Work
You don't need to be a blacksmith to work metal into your art. For example, artist Douglas E. Taylor hammers and cuts scrap metal from old tin cans, and uses screws, nails and staples to affix metal pieces to his collage surface. If you want to mimic Taylor's technique, you'll need a more robust collage surface, such as wood or particle board.
Working With Digital Images
Some artists move beyond regular photographs and magazine pictures and use technology to help them create their visions. If you have a digital camera, you can take photos and manipulate them using photo editing software. If you have the money, purchase Photoshop to add lighting and color effects. You can get basic photo editing software for free from Photoscape.
