Protect the work surface with a sheet of newspaper or some plain paper.

You can wear gloves to avoid staining your fingers with food coloring but I found the dye washes away fairly easily.

Add clear glue to the center of the glass. Add a couple of drops of food color to glue (we added yellow dye). Mix the two together on the glass using your paintbrush.

Add glitter glue to the surrounding area and add a few drops of food color throughout (we added purple). It works best if you paint one color at a time to avoid the colors mixing together and turning brown. Paint a few swirls to resemble outer space.

Continue working outwards adding new colors and mixing the existing color on the glass. The more dye you add, the darker the result. It’s best to work fairly quickly so that the glue doesn’t harden before you had a chance to blend the joining colors.

If you’re not happy with the painting, you can easily wash it away with some warm water even after it’s dried fully. When you’re satisfied with the masterpiece, leave it to dry fully before placing in the frame.

Insert into a frame and enjoy!
