Written instructions for a triquetra with circle. The instructions are mostly written, with a diagram to help with the crossings. (If anyone knows how to chart something that overlaps itself, please let me know!)
One size is given, and finished size depends on the yarn and hook used. Dishcloth cotton and a 5mm hook produced a knot that was 3.25” by 3.75” (8.25mm by 9.5mm).
