I find this Celtic Circle Knot really beautiful and imagine it depending on the used yarn as an ornament on a card, a pin or a hair decoration.
But I can’t show my own photo yet because my fingers were up until now much too clumsy for it ;-))
And when I have worked it out I can possibly even design my own Celtic Knot ;-)
