The intricately woven knot is a symbol of marriage in many cultures. Nowhere are these designs more pervasive than in the Celtic cultures of Europe. The examples shown here illustrate a few of the many Celtic Wedding Knot designs I have created for different people. In addition to the basic form, there are endless variations on the type of knot, colors, placement of the wording, and so on. Knotwork can also be added within the borders or symbols of any other certificate.
