How to Make Glass Block Light Boxes


Glass blocks are used to construct shower walls, in the construction of bars and even to build dividing walls that are somewhat see-through. Glass blocks, however, also can be used for a number of decorative craft projects including making light boxes. Make your own light box that features your own art work or a fun design you found online to add to the lighting of a room as well as the room's decor.

Things You'll Need

  • Glass block with pre-drilled hole in the bottom
  • Measuring tape
  • White printer paper
  • Printer (optional)
  • Colored pencils or pens (optional)
  • Paper trimmer
  • High grit sandpaper
  • Decoupage
  • Foam brush
  • Old credit card (optional)
  • White Christmas lights
  • Measure the front of your glass block so you know what size your design needs to be to fit on the block.

  • Print or draw a design to put on the front of your block. Make sure the design fits in the dimensions of the front of the block. Mark an area on your sheet of printer paper with those dimensions if you plan to draw your own design so you can stay within the limit.

  • Trim the piece of paper with the design on it to the dimensions of the front of the block using a paper trimmer to get smooth straight edges.

  • Use high-grit sandpaper to sand the front of the glass block to make it a little rough so the decoupage will adhere.

  • Apply a generous layer of decoupage to the front of the glass block with a foam brush. Cover the entire front side with the decoupage.

  • Adhere the trimmed-down design to the front of the glass block. Line up one edge of the paper with an edge of the glass block and slowly lower the paper down, working your way across the glass block, smoothing out air bubbles with your hand as you go. Use an old credit card to smooth out any air bubbles if necessary.

  • Apply another layer of decoupage over the top of the piece of paper to seal it to the glass block. Make sure the entire surface of the paper is covered and that you brush past the edges of the paper to seal them to the block. Let the decoupage dry for at least two hours.

  • Stuff a strand of 50-count or 100-count Christmas lights through the hole in the bottom of the glass block, leaving the plug hanging out of the hole so you can plug in the light box.
