(Edited November 17, 2014)

I use Daniel L. Isdell’s Celtic knot font to design my Celtic knots.

I use MS WordArt to warp them into circles.

I propose a series of pages showing open-ended Celtic knot sections and the resulting circular Celtic knots.

I will color Celtic knots with multiple cords accordingly. The blank knots consist of a single cord.

The knots shown below come from a single knot section linked together.

Even-numbered sections result in multiple intertwined cords. Odd-numbered sections result in one continuous cord.
