Things to see and do
The United States Institute for Theatre Technology is having their annual conference and stage expo on March 18-21, 2009 in Cincinnati, OH. One of their Wednesday classes is the apparently popular “Knots, knots, knots” a class on knots perhaps as relates to stagecraft? (via)

More of the similar. 8) Octagonal (8 sided) good luck knot. Again, as is traditional in Chinese knots, for an octagonal knot, the structural loops are overlapped 3 times. In this case you would be tying 3-over crowns. The corner versus side ears might start getting a bit confusing at this point. Remember that both sides of the side ear come out of a single point (the long ears here) and the corner ear wraps around other cords (the short ears here. But, of course, the ear length in your knot is entirely up to you).
