Glitter Glue Containers
Create a beautiful, glittery container to hold pens, pencils or other items. Use a clean clear glass jar. Draw a design on the jar with glitter glue. The design can represent something or can be abstract. Use various colors for a colorful effect or choose a couple of colors. You can draw simple flower designs on a jar or clear vase to create a flower vase for someone special.
Glitter Glue Ornament
Plain glass ornaments can be made beautiful when embellished with glitter glue. Create interesting designs on a glass ornament by using the tip of a glitter glue pen to leave a trail of glitter glue. The ornaments can be used as Christmas tree ornaments or, when done in pastel colors, can be used as Easter or springtime decor. Hang the ornament from an ornament stand for use all year long.
Glitter Glue Window Decorations
Lay wax paper down on the table and use glitter glue to create a design or write a message. After the glue dries, carefully peel the glue from the wax paper and use tape to hang the design or message to a window. This method can be used to make sparkly winter snowflakes or "Happy Birthday" greetings. Use multiple colors of glitter glue by allowing one color to dry before adding another colored glitter glue to the design.
Paper Crafts
Create paper crafts with glitter glue. Greeting cards are a nice craft for kids to make and give to loved ones. Create greeting cards with construction paper and other craft items. Use glitter glue to create the wording on greeting cards and other decorative elements. Use glitter glue to draw simple flower patterns on greeting card envelopes too. You can also use glitter glue to embellish other paper crafts like bookmarks.
