Preparation: unbreakable bench, garden hose, drill bit and the drill guide – everything staying secure in place.
6 mm hole with sharp edges has to be covered with a grommet.
Bottle – washed, stickers – removed. Time to install the lights. Shrink tubing in the same colour as the cord.
Cable tie will prevent the cord from sliding in. One of the Christmas lights inside the bottle will prevent the cord from sliding out.
Looks really nice, even in April.
