This is a Rosary sample with large beads.
As you can see from the jpg, I have a standard Mission Rosary with mission cord #9 and 6x8mm beads.
The 10mm, 12mm, and 8x11mm beads are strung on the standard mission cord.
Do you think the mission cord will be strong enough to withstand a 15 or 20 decade Habit Rosary?
The 12mm bead on the green cord has a much large larger hole. The size cord may be #36 but I am not sure.
