Cindy...You can wrap in twine, ribbon, yarn, tape, use lace, add bows. You can also use beads such as pearls or fake diamonds, etc. Try adding jewelry (vintage is wanting that look). There is so much as well as painting clear bottles using Elmers glue, dot of food coloring and a sponge brush. Looks streaked when wet but very pretty when dry. Good luck, hope this helps.
