Step 1 - Cut two, 3-foot lengths of cording and fuse the fiber ends with heat from a flame or hot nail.

Step 2 - Using a soldering iron or hot nail, melt pairs of 4 mm diameter holes opposite each other on the seams of bottle components "A," "B," "C" and "D" as in the drawing.

Step 3 - Tie a simple knot in one end of each cord, then thread each cord through the hole in the rim of "D," from the inside to the outside the knot will be on the inside of the reservoir unit "D." Continue threading the cords from the outside of unit "C" to the inside to the outside of the base of "B," then work inside through the holes just below the hip (top) of "B,"

Step 4 - Thread the cords from the inside of column top unit "A," then tie the ends of cords together with a square knot.

Hang your bottle on a hook and it is ready for loading.
