One can make one's own decorative bottle for storing holy water. Get a
nicely-shaped bottle --preferably one with a flat surface on one side --
with a gold-colored or silver-colored screw on top, such as the bottles
Soak the bottle in hot water with a little alcohol to totally remove
all paper and sticky glue, and let it dry thoroughly. Make a stencil
of the words "Holy Water" ("Aqua Benedicta" in Latin), or a stencil of an
appropriate symbol, such as the fish, or a symbol of Baptism. Use a chemical
etching agent to etch the glass with the words of symbols you've chosen.
Chemical etching agents can be found
( will open in a new browser window) and in craft stores such as Michael's.
Follow carefully the instructions that come with your etching agent!
