I have 15 glass bowls for sale for centerpieces. They are the shallow glass bowls often used to float candles or flowers. They look like the ones in this link below but are 10 inches, not 7.5 inches like these.
http://tiny.cc/cf41pWe used them to float gardenias in and had candles around the bowls.
asking $3 each. I live in the Alexandria/Arlington area
