Combine 2 pairs of adjacent (and spaced-apart) strands and join them in an overhand knot, thus linking all the strands together.
In staggered rows, link the overhand knots so as to create the diamonds of the net.
At the bottom of the jar, tie overhand knots all the way to the bottom of the jar. Pass a strand through the knots, tighten to stick to the glass and tie a double knot.
Pass the ropes flush with the overhand knots. To secure the ends of the strings, brush them with quick-setting glue.
