Decoder glasses have been around for many years, but have recently experienced a resurgence. 3D technology now appears in movies, television shows and even commercials. Make your own pair of 3D decoder glasses in just a few minutes, with items purchased from a local art or crafts store. Who knows what 3D image or secret message you may come across next?

Draw a flattened pair of glasses onto a piece of cardstock. Use an existing pair of glasses as your model, or measure your head to determine how long the sides need to be to reach your ears.

Cut out the drawing with a pair of scissors. Poke a hole through the middle of each lens with the scissors, then cut the lenses out.

Place the acetate on top of the glasses and trace each lens with a marker. Trace one red lens and one blue lens. Cut out around the traced pattern a little bigger than actual size. This will leave enough room on the acetate to tape each piece to the cardstock.

Tape the blue piece of acetate to the lens that will be on the right eye, and the red acetate to the lens that will be on the left eye.

Fold the ear posts down.
