Making mission rosaries (rosaries to give away) is inexpensive and a great fellowship project for all ages able to string a bead without eating it.   :)  
Everything you need can be purchased at Our Lady's Rosary Makers out of Kentucky.
The equipment for all-knot rosaries can be purchased locally from Illuminated Ink, a Catholic mail-order business in Colfax.
