Tips & tricks
Piece of glass - any size Mod Podge Gloss Black acrylic paint Glass paint, low opacity Disposable bowl/cup Squeeze bottle Paintbrushes
Combine about ½ cup of Mod Podge and several drops of black paint in the disposable bowl and mix well. Move tinted Mod Podge to the squeeze bottle.
Place the glass on a flat surface (over photo you want to stencil, if desired) and gently squeeze the bottle to draw an outline of a pattern. Go slow so that the lines appear as even as possible.
Once the outline of the design is complete, set aside to dry completely.
