Lucet patterns

While doing some research on making friendship bracelets I ran across a link for making cordage with a lucet. I have done this in the past and still have a small lucet. I did not find many patterns to cut a lucet so I made some up for the public at large.
What is a lucet you say? It is a wood, bone, plastic forked tool to make decorative cord, for clothes for decoration, to use an bracelets, etc.
