Reverse decoupage is decoration technique when print and paints are applied underneath the glass.
But to paint inside the bottle is very difficult 🙂 so we will paint on the back side of the bottle.
Napkins for decoupage
Divide the napkin by removing all the white layers. It is only the patterned top layer of the napkin you want to use.
Put a napkin under the bottle and tear off the edges.
Glue the napkin to bottle upside down with decoupage glue or Mod Podge. I used school glue.
Once dry paint the bottles with acrylic paint color of your choice.
Break out the masking tape! Put a large working are on the front of the bottle.
When the paint is dry, remove the masking tape.
Glue motifs from napkin to the other side of the bottle.
And when the paint is dry, apply gloss varnish.
