With this idea, it is important not to cut the desired motif, but to tear it out of the napkin . This has the advantage that the edges of the napkin motif will hardly be visible later on the lampshade .
Remove the bottom layers of paper from the napkin. Coat the lampshade with napkin varnish and then place the motif on top. then coat everything with another layer of napkin varnish.
Once this has dried, you can place the shade on the lamp base, screw a suitable bulb into the socket and then set up your new lamp in your home.
