Hemp & Stone Necklaces

These are two necklaces I made with hemp & large stone beads. I listed the budget as "almost nothing" since the beads were given to me by my crafty mother-in-law. (The smaller brown beads are glass, not stone.)
I also can't remember how long they took. I would like to post a tutorial, but I don't have any more of the square beads (so I can't take photos of the process). However, I can tell you they were made with very basic knots.
