First paint some areas of the boat with white craft paint. Once dry, cover with the soft glass mosaic as desired.
Then mix some grout with water to make a creamy mixture and brush it into the joints of the mosaic.
The excess grout can be easily removed with a damp sponge. Once the grout has dried, you can wipe the stones again with a dry cloth to make them shine again. Then take the grout finish and coat the mosaic with it.
To protect the boat from moisture, coat the wood (inside and out) with wood stain varnish.
If the boat is to be planted with plants, it is recommended that the inside of the boat is also covered with a film.
Finally, attach the fairy lights above the plant.
