I love to give 'Vases' if I have not already given one, to that person.
I think they are a wonderful item in the house, and encourages people to have flowers from time to time.
I give mainly plain and simple, tasteful glass or crystal.
You can never have enough, then tend to break over time.I sometimes find gems in the second hand stores that are just about new.
Maybe $5 - $10
Otherwise, I like to give a small gift...because it is a wonderful time of year, and second hand shops have great stuff.
You have to have a very strong pair of glasses, to make sure there are no chips or cracks on the item.
The art of giving is two fold, makes you feel good and the receiver feel even better.
