Knot a Problem — Help

Create Celtic Knots

With the icon set to scissors (), you can design your Celtic Knot by drawing walls. These are breaks in the knotwork where instead of crossing, the ribbons turn back on themselves. By default, the walls are drawn symmetrically (this can be changed in the settings).

Zoom In/Out

With the icon set to the magnifying glass (🔍), use pinch to zoom and drag to move the knot around. Double tap to reset the zoom so that the knot fits on the screen.


With the icon set to the plus/minus (±), you can resize the knot itself adding to or subtracting from each edge.
