I sold mine also except for a couple.  I had one that broke off about 19" down so I put that in a vase up in the front and it lasted about 5 days.  I never recut it though, it was in crystal clear.  I have heard that they will last 2 weeks or more.  Doesn't seem like that is the case for me.  I am thinking maybe it is because of the altitude where I live in Rapid City, SD.  I am alittle frustrated because I really wanted to use them more.  I'm still thinking I will try some more.  I did order 1 box 60c for v day from Doug.  I have some 70c Forever Young coming in tomarrow, Thursday, from them.  I'm going to take a long at those.  Did you order any more Hearts for V Day?
