How Can I Make Real "Medieval Rose Beads?"

Lovely and historically significant, rose beads are simple to make and will fill the room with fragrance.  They are the traditional beads from which "rosaries" take their name.

Take 4 cups of rose petals, 4 cups of distilled water, 1 teaspoon of sandalwood oil, and 1 teaspoon of rose oil.  Finely chop the rose petals and add to a pot, covering with distilled water (only enough to cover, no more).  Heat this uncovered for 1 hour without boiling.  Remove the mixture from the heat and cover to set overnight.  Repeat this process for 4 more days and then roll the mixture into small beads, rubbing the hands with 1 drop of sandalwood oil  and 1 drop of rose oil for every 5 beads.  Squeeze out the liquid as you roll the beads, then thread with a large needle on fishing line or other thick thread.  Let dry.  To refresh the scent of the beads, simply sprinkle them with rose oil periodically.
