I guess that is related to necklace making :) Here are the steps she needs to follow;
Decide how long the necklace should be and then cut the string as decided. The next step would be to tie a knot but not very tight, a loose one to one side of the string. Next she needs to put the beads into that string in an arranged and beautiful color combination style. Finally when it is done, the loose knot needs to be opened and tied to the other end of the string with the caution that no beads should fall out.
