Celtic Knot Draw is a tool that allows users to design custom Celtic Knots by switching intersections in the knot’s from crossings, to parallel horizontal or vertical bands and redrawing the modified knot automatically.
.
The size and complexity and colors of knots are also set by the user.

Click on the points highlighted as the mouse passes over them to cycle between places where Knot bands are vertical, horizontal or cross.

Save knot snapshots as image files and save your work in sessions files to be loaded and continued whenever you want.

The number of points were a new knot could cross itself and image size are configurable.

The ways that a Celtic Knot can be guided to be a work of art are subtle. Enjoy.
