Summarize:

Apply the glue and trim to 1 side of the label at a time. If you are decorating the front label, consider doing 3 rows of rhinestone trim. Use a thin trim for the first and third rows, and a larger trim for the middle row. Use a thin, simple trim for the back label. You don't have to use rhinestones for the middle row. Try pearls or even studs! Some bottles have a round stamp or seal near the top, right between the neck and label. Choose a large rhinestone, then glue it right over the stamp or seal. Glue 1 to 2 rows of tiny rhinestones around the larger one for a fancier look. The large rhinestone should be large enough to cover the stamp or seal. For more variation, use tiny pearls for the first row, and silver rhinestones for the second row. If all of your rhinestones are the same shape, size, and color, your bottle may look monotonous. Give the bottle a quick coat of a clear-drying glue or spray sealer, then shake some glitter onto it. This works especially well over smooth, pearl trims. If you are using spray sealer, it must be glossy, or you will dull down the rhinestones. Use glitter that is the same color as your rhinestones to help blend it in some more. Extra-fine glitter will look pretty, but you can use chunky glitter instead, or even a combination of both! If you covered your entire bottle with rhinestones, it may look a little monotonous. Let the bottle dry first, then add larger rhinestones, gemstones, or flat-backed pearls on top. Use these sparingly; do not cover the entire bottle with these. This works especially well over a pearl trim. The rhinestones will help add some texture. Cut a length of ribbon and tie it into a bow. Glue the bow to the neck of bottle, then cut the tails of the bow into angles. Glue a fancy gemstone or brooch to the center of the bow for a more detailed touch.
Outline labels with rhinestone trim for a fancier touch. Glue large, fancy rhinestones over round stamps or seals. Break up monotony and add texture with glitter. Layer larger gems and rhinestones over tiny ones. Add an accessory, such as a bow, if desired.
