Some things that make stunning vases for a simple and understated look are:
Peanut Butter glasses
vintage style drinking glasses or dessert cups
Mason jars in various colors
Tiara glass (which is this absoultely gorgeous amber color glassware! but also has some other colors)
If you don't have time to hit the market, try local yard or tag sales (check the news paper listings)
Ebay is also another great place to purchase anything vintage, but remember the shipping might cost you just as much as the item itself!!
Adding single blooms, such as dahlias, zinnias, gerbera daisies, garden (cabbage) roses or orchids make a simply gorgeous statement. Add a ton of candle and you've got the most romantic setting ever! Of course, for most of our weddings these little vases are an addition to the main centerpiece. Adding that touch of detail and drama. The more detail the better!
