Introduction: Stained Glass Mosaic

One fun stained glass project that you can do at home is a stained glass mosaic. It is a very fun and easy project that can brighten up any room. There are a lot of different things that you can do with the mosaic. You can turn it into a table, you can hang it on the wall, you can turn it into a cabinet, there are many different things that it can be. During this instructable, you will see different stained glass mosaic that show the different steps of completion.

(I suggest you read the entire instructable before getting started)

What you will need:

  • Different coloured stained glass
  • Plywood
  • Strong glass glue
  • Sanded grouting


  • Jig saw
  • Sander
  • Carbon paper
  • Pencil
  • Elmer's rubber cement
  • Thin Sharpie
  • Wheel glass cutter
  • Glass pliers
  • Glass grinder
  • Small cloth
  • Safety glasses/goggles
  • Rubber gloves

Step 1: Cutting the Wood

The first step is to prepare wood.

  • Using a jigsaw, cut out the wood into the shape in which you want it to be. (In my example above, the wood is a circle.)
  • Once cut, smooth out the edges of the wood with the sander.

Step 2: Sketching and Selecting the Stained Glass

WARNING: When handling stained glass, be very aware of the edges of the glass they can be very sharp. If you find that you have cut yourself, just make sure to have the cut cleaned and bandaged before continuing with your project.

  • Find a design that you want to make the stained glass mosaic out of.
    • Look online for designs or in stained glass books for some option.
    • Be sure that you have two copies of the design that you want to build (if you only have one, then you can use some sketching paper to sketch your second copy).
    • Using the carbon paper, sketch your design onto the wood to better show the placement of each piece.
  • Determine all the colours of stained glass that you want to use and be sure to have enough of each colour.

Step 3: Preparing the Glass

The next step would be to cutting the stained glass into the general shape that you want it to be.

  • With scissors, cut out your second copy of the design into the pieces.
  • Sketch the pieces onto the stained glass with the Sharpie, you can use the rubber cement to keep the pieces on the glass, the rubber cement makes it easy to place and remove the pieces of paper from the glass.

Step 4: Cutting and Grinding

The next step into this project would be to cut out the stained glass into the pieces that you want them to be.

  • Using the wheel glass cutter, make a line of separation for where you want the glass to be cut, do not make this line too curved as the glass may not separate the way you wanted it to
  • Using glass pliers to separate the glass.
  • Using the glass grinder, grind the glass into the shape of the design that you want it to be.
  • Put the piece on the wood to determine where you would need to grind a little more.
  • Using the cloth, make sure to clean the glass after every use on the glass grinder.
  • Once you feel the piece is in its best shape, glue it in place using the glass glue.
  • (Above you can see my progress from a few pieces all the way up to having all the pieces glued in.)
  • If you wanted to put some glass on the edge, you can make a bunch of rectangles and then just glue them to the edge of the wood. (as shown in last photo)

Step 5: Grounting

Once the glue is dry, the final step would be to adding some grouting.

  • Mix SandedGrout (colour of your choice) with water (read SandedGrout box for the ratio) and spread the solution on your mosaic filling up all of the cracks. Wipe gently with a damp sponge. Let dry for 24-48 hours.
  • Once dry, your stained glass mosaic is complete.

Step 6: Extra (Optional)

Once dry you can add legs to turn it into a table or you can attach a hook onto it and have it hang on the wall.
