  • A rectangular glass block measuring 3.6 inches by 7.6 inches by 3.06 inches

  • Pattern to draw onto glass (at right)
  • Permanent marker (optional)
  • Gallery Glass window paints in Crystal Clear, Snow White, and your choice of colors
  • Gallery Glass liquid leading
  • 1/4 inch flat paint brush

Painting the Vase

  1. Make sure all stickers are removed from the block and clean any remaining glue off with Goo Gone followed by a glass cleaner, such as Windex.
  2. Download and print out the Celtic cross pattern onto transfer paper.
  3. Transfer the design onto the glass following the instructions specific to your transfer paper. (You can also draw the design freehand using a permanent marker.)
  4. Use the Gallery Glass liquid leading to go over the design.
  5. Set aside and allow the liquid leading to dry at least four hours to overnight.
  6. Choose your colors of Gallery Glass window paints. The design here uses Ivy Green and Gold Sparkle. Paint the inside of the design as desired.
  7. Set aside and allow the colors to dry overnight so there is no chance of smearing when finishing the outside of the cross.
  8. To frost the glass around the cross, apply a thin coat of Gallery Glass Crystal Clear. Set aside to dry for about an hour. Then use Snow White with a 1/4 inch flat paint brush to stipple on the white paint. Allow this to dry overnight before adding water and flowers to your vase.

You Are My Sunshine Nightlight

You are my sunshine glass block nightlight

Make a personalized nightlight for your little one with a small square block and a clip-in light kit that uses a standard nightlight bulb. This is a simple decoupage project that the kids can help with.

Materials Needed

  • A square block measuring 5.6 inches by 5.6 inches by 3.75 inches, with a removable stopper and opening
  • Goo Gone cleaner
  • Yellow construction paper
  • Acrylic craft paints in orange, peach, brown, and black
  • Mod Podge decoupage glue and sealer
  • Sponge paint brush
  • Small and medium detail round paint brushes
  • Sharp knife
  • Clip-in light kit

Making the Nightlight

  1. Remove all stickers from the block and wipe away any remaining glue with Goo Gone followed by a glass cleaner.
  2. Draw or trace an outline of a sun onto the construction paper and cut it out.
  3. Apply a thin layer of Mod Podge decoupage medium to the glass block with the sponge paint brush. Center the sun on the block, press gently to adhere, and apply another thin coat of Mod Podge over the sun. Allow to dry for about 15 minutes.
  4. Use a small detail paint brush and acrylic craft paint to paint the detail onto the sun. Wait about five minutes before continuing to the next step of painting.
  5. Use a medium round paint brush and black acrylic paint to freehand the script "You are my sunshine" onto the block, arranging the words as desired. Allow five minutes for the paint to dry and then go over them once more with the black paint.
  6. When the paint is dry, apply another two coats of Mod Podge to seal your design, letting each coat dry for about 15 minutes.
  7. To assemble the light, pull the plug from the block and carefully cut out the inner part of the plug with a sharp knife, leaving a ring of about 1/8 inch. Insert the clip light so that the clip fits snugly into the plug ring. The light is now ready to use.

Lighted Centerpiece

Make a unique centerpiece or entry way decoration with a larger square block filled with LED tea lights. The ribbon on this block can be changed with the seasons so that it always matches your decor.

Materials Needed

  • A square glass block measuring 8 inches by 8 inches by 3 inches, with an opening at the top
  • Clear vase filler such as Color Fill
  • At least two yards of gold mesh ribbon
  • At least three yards of patterned, wire edged ribbon
  • Hot glue gun
  • Three LED tea lights found at any craft or dollar store

Assembling the Centerpiece

  1. Remove all stickers from the block and clean the glass with Goo Gone and a glass cleaner.
  2. Measure the length of mesh ribbon you will need to go from one side of the opening in the block around to the other, creating a stripe along each side of the block. Do this from front to back as well as from side to side.
  3. When your glue gun is hot, glue the ribbon vertically to each side of the block.
  4. Fill the block about one-third of the way up with Color Fill vase filler.
  5. Set the LED tea lights on top of the filler in a row.
  6. Use the patterned, wire edged ribbon and follow these simple instructions for making a gift bow, or use your favorite style of bow to top the centerpiece.
  7. Attach the bow to the top front of the block using hot glue. Adjust the bow to make sure that it will sit level when the glue is dry.

A New Blank Slate

There are plenty of different design options for glass blocks. They can be stained or have a design etched onto them. You can light them with small strands of Christmas lights or even use one as a small terrarium. Pick up a few different sizes and create one-of-a-kind pieces for your home.
