Do It Yourself: Making A Simple Wall Mirror Mosaic

This is a wall mirror mosaic. Mosaics are easy to make, easy to sell and make a great gift idea or a home accent.

The first thing in making a mirrored wall mosaic is deciding what shape and size you want your art to be. After you have decided the size and shape of your design, then you will need a piece of plywood cut to your design and size. If you have a jigsaw or band saw you can quickly do this. If you do not feel comfortable using these power tools, then other choices would be a trip to the local home store and have the pattern cut for you, or your local craft shop will usually have a section of wooden items.

Choose a pattern you like to go with the mirror. There are a variety of sources for choosing a pattern, select one from your computer, purchase one, or simply design your own. It can be a simple geometric pattern to a more complex design. Scale the pattern to fit the base. Any copy shop can do this for you.

Trim Molding

Although this is totally optional, I like to create a frame for my project. Cut trim molding into four sections, mitering the edges at a 45-degree angle. A miter box works well for this. I add the frame on top of my base along the edges. Secure small strips of wood to the backside of each wood piece with brads. Slip the base into the frame. There should be a lip created with the molding to hold the base in place. You can use L-shaped brackets to secure the base and frame. Now that you have the plywood base I would lightly sand and primer it. Draw the pattern directly on top of the base.

Be sure you wear safety glasses when breaking glass. Select the main background color for your project and place it into a large paper bag. Break the glass by hitting it with a hammer into random size pieces. Use small containers to hold each color of glass. Repeat this process for each color.

These are some uses for the glass tools. Use a glasscutter for pieces that you want a more precise cut. Hold the cutter as though holding a pen. Start at the far edge and pull the cutter toward you. A light touch on the cutter will do. You will hear a crackling sound as you pull the cutter across the glass. Once you start your score do not stop until you get to the very edge without dropping off. Do not go over the same score, as this will damage the cutter. You can further shape the piece of glass with the nippers. The running pliers are good for breaking a straight cut.

My sample project has a rectangle base eight and a half by eleven inches. The mirror is also rectangle four and a quarter by five and a half inches long. I using the cutter to score straight and slightly curved pieces of glass. These longer pieces I will place horizontally across the top and vertically on the sides. The rest of the pieces I used a hammer and a paper bag to break in small random pieces to fill the rest of the spaces. Make sure that there is a gap of at least one-quarter inch or less.

I have all my pieces cut and ready to assemble. Lay all the pieces of the pattern on the base for a dry fit first. Make any adjustments needed at this stage. You can use the glass tools to shape any of the pieces as you go along. Use the cutter and running pliers to make straight cuts for the edges of the pattern.

Apply glue to the piece of glass and press into place following your pattern. For small pieces you could use tweezers. I will glue my focus pieces of glass first. For my project the focus pieces would be the mirror and the long straight and curved pieces. Next I would fit the filler pieces.

Allow the glue to dry completely. The next step is to grout the project. Mix the grout according to label directions. You can use a grout float or craft sticks to gently push the grout into the small spaces in between the glass pieces. Use rubber gloves to protect your hands. Remove as much of the excess grout as possible.

Allow the grout to dry completely. Wipe clean with a sponge and bowl of water. Apply a sealer to the project. Add decorative hooks and your project is ready to hang. This would make a beautiful accent piece in any home d├ęcor. Now that you can do a mosaic project, the process is the same for doing other projects. This project would make a beautiful gift for anyone.
