It’s an early American form of braiding for all kinds of uses such as drawstrings for reticules, attaching a knife to a belt, decorating hats or used to tie hats on. It can be as light or as heavy as required, depending on the rope or string used. The tradition goes back at least to Renaissance times an up until cord was made by machines. It is faster and more economical than Kumihimo braiding.
I will demonstrate a flat and square braid using nylon cord or rayon thread. I will have handmade lucets to practice with or for sale ($35-40) and books from Lacis ($12 at cost) on more advanced techniques such as two and three color braids.
There is no homework.
