Here's how I made them:
Clear acrylic plastic
Black Elmer's painters pen
Gold metallic paint
Rubber stamps - *optional
StazOn ink pad - *optional
All the paint is applied to the back of the plastic. Because of this, all words have to be written backwards.
With a painter's pen, draw out your choice of word or image backwards on the acrylic.
Once the black paint is completely dry, paint three layers of gold paint over it. Let the paint dry between each layer.
Cut out a piece of felt and glue it to the back of the gold. Let dry.
When you flip over your piece, it should look like the picture above. I also experimented with rubber stamps for this project. For the bottom piece, I stamped it instead of using the painter's pen. The rest of the steps were all the same.
