To stick the labels on the glass bottles, a cup of milk does the trick!
Fill the bottom of a dessert plate with milk (no soup plate, the edges are too high).
Hold the label on one side and roll it upside down on the milk surface.
Take the other side and do the same.
Apply the label flat on the body of the bottle so as not to create an air pocket.
Wipe with a damp sponge to remove any drops of milk that may have leaked.
This "glue" ensures excellent adhesion to labels. Afterwards, they are easily removed with water.
