On a recent visit to Cape Cod, I was taken aback by the creative and skillful techniques for tying a knot.
For someone who only knows how to tie a shoelace knot, and one that comes undone frequently, I was truly impressed at this exhibit. I found myself admiring the fact that not only do these knots perform specific functions, most of them are beautiful looking too. A great example of form and function.
