I have found quite a bit of success with tying 4 - 5 stems together with string, and then putting them upside down in a paper bag. I've punched a hole in the bag first. The main thing I find is that I have had to find a warn airy room to hang them. When I used to hang them in the pantry, where we keep the door closed, I had problems with mold. So now they get hung in the kitchen/dinning room. It is one big room in our house and I keep them away from the windows and doors near the middle of the house.
