All Celtic knot patterns in our collection are accurately drawn using a grid and all geometric elements of patterns are lines and arcs. On the internet it is quite easy to find tutorials on how to create them by yourself. If you do not have time to learn, you can download a free application for creating Celtic knot patterns called Knotter. Celtic knot patterns can be very easily drawn by using 2D CAD or vector graphics applications. From experience we can say that the non-parametric 2D CAD applications are more suitable for drawing Celtic knot patterns, because 2D CAD applications have more advanced commands for drawing geometry in relation to applications for vector graphics. Parametric 2D CAD applications are also suitable for drawing Celtic knot patterns but drawing is more complicated than in the non-parametric 2D CAD drawing applications.
We hope you like our collection of Celtic knot patterns and you will find one that suits you, thus saving you valuable time.
