Put your corners on the knot now, but again, only put them within the rectangle.

Continue the lines of knot from where they branch out from within the rectangle around the outside. They should join up on the other side, as shown in the diagram, so that there are no unattached ends.

Pick a place where the lines criss-cross, and erase it so one passes over the other. Erase the other two criss-crosses so that the over/unders alternate. If you want to be notified via e-mail when new Tutorials are up and running, sign up here!
