Are you interested in making the rose-scented beads which are often
used in rosaries? There was a very explicit article in Bead and Button
several years ago on that topic, and you might find something at
BeadNet http://www.mcs.net/~simone/beadnet.html
There was also an extensive thread on rose beads in rec.crafts.beads
several years ago. Sorry I can’t be more specific, but this should
give you a general direction to head.
