First thing to do is to collect transparent glass bottles and wash their interior and exterior using hot water and detergent (it is recommended to use liquid detergent to avoid stains on the glass).
Allow to dry completely until there is no trace of moisture. Once ready the bottles empty acrylic paint (obviously choose Christmas colors) inside and turn the bottle in all directions so that the paint covers the entire surface.
Do not hesitate to add more paint if the one you put is not enough to cover the entire bottle. Once the paint has covered the entire interior of the bottle, you should turn it over to allow excess paint to drain. This step can last from a few hours to a full day, as the paint must dry completely.
Now the bottle is painted inside, which allows you to decorate the exterior to your liking, using Christmas elements, and if you prefer you can also add small details with painting of the same type. Look at all these beautiful examples we have compiled from the internet:
