You can edit the woven pattern below to create interconnected celtic-style knots. Click the Edit button to show the primary (small) and secondary (larger) grid points. Connect two adjacent secondary points (non-diagonal) to form a knot boundary by clicking on one point and then another neighbouring point. If two non-adjacent points are selected, a rectangular boundary with the selected points as diagonal corners will be drawn, if possible. Click on the grey midpoint of a boundary to remove it. Click Show to reveal the knot pattern.
