Sea Glass Mosaic

Mermaid tears. Beach glass. Sea gems. Sea glass. Whatever you prefer to call them, they have dazzled beachcombers, crafters, and artists for many years.

  • Sea Glass
  • Frame with the Original Glass
  • Silicone
  • Drawing Paper 
  • Marker or Pencil
  • Tape
  • Tweezers

Step 1: Organize sea glass by color. 

Step 2: Sketch your design on drawing paper. 

Step 3: Flip the frame over and tape the design onto the back of the glass.

Step 4: Flip the frame over again with the front of the glass facing upwards with your design behind it. 

Step 5: Without gluing, arrange your glass over the design. Make changes in the arrangement of glass pieces if you cannot find the right size at first. It is similar to a puzzle! 

Step 6: Once you have a final arrangement, glue each piece using 100% silicone. Use tweezers to help with the smaller pieces of glass. 

Step 7: Allow the silicone to dry and then hang your sea glass mosaic on the wall. If able, hang it in a window to turn it into a beautiful suncatcher.
