Ok heres the deal. The only one of these I have ever done was in college, and that was based on a hedgerow. (Quite pleased with it actually). anyway have never based GOH but have an order for Monday. Have looked through all my reference books and not a single one - HELP -HOW MANY STEMS DBLE XANTHS DOES IT TAKE!!!! Don't want to overorder but am worried about leaving myself short. It is the equivalent of a large pillow, for example. Any offers?
