The knot is made out of rows of sc, with strategic increases and decreases to cause it to bend. The pattern should be accessible to a motivated beginner.

This piece can be worked in any gauge. The finished dimensions are roughly 80 sc wide by 30 sc high. In crochet cotton, it is about the size of a bookmark; with medium yarn and a 4mm hook, it’s a good size for a trivet.

The knot is worked in two pieces, each of which is seamed together at the end. The seam is hidden underneath a crossing, so the piece has a right side (where the seam is hidden) and a wrong side. Using the border shown in the pictures further differentiates the right side from the wrong side.

This pattern appears in the ebook A General Method for Knotwork Crochet. The ebook includes instructions for making crochet patterns from any rectangular Celtic-style knot. This knot is one of two examples in that book illustrating the method.
