There are many reasons why you might want to dry your roses. Some people just want to keep a memento of a special moment. Perhaps they are a part of a wedding that you went to; maybe they were a gift from a mate, friend, or family member.
There is also the problem of wilting and drooping roses once they are placed in vases when they are given as gifts. Roses look so beautiful in any room that they sit in. They add an elegance that is unsurpassed by any other flower.
