I will be teaching you how to make glass paintings!
Supplies
-Glass, best if you use picture frame glass

Sketch Your Art

Sketch desired drawing onto a piece of paper. Personally, I think portraits look best on glass, you can also print out an image to trace on the glass. Make sure this fits the glass that you will be using.
Trace Your Drawing

Trace the art using a black permanent or posca marker. You should get an outline of your art. Make sure you don't add any shading yet!
Adding Color

flip the glass over to the back (the side you didn't draw on) and color in the drawing using paints or posca markers. you can add shading using different colors, make sure you don't leave any gaps or spaces!
