It is important to get the number and spacing on a rosary correct.
On Muslim and Buddhist prayer beads there are no spaces except at
the beginning/end, but with the rosary there are spaces all through.
A cross, 1 bead, space, 3 beads, 1 bead…then a triangular piece or
whatever shape will join three pieces together. Once you get past
the triangle there are 10 beads, a space, 1 bead, space, then 10
beads again. This pattern is repeated so that there are 5 decas that
lead back to the start of the triangle.
