A selection of simple celtic knots. As requested, I've now added each of the knots separately - nicknamed according to their position in the thumbnail (top or bottom row and numbered 1-3 from left to right). Enjoy!
just re-cropped Liftarn's post his current post was too big (3560x3540 pixels) for my screen and i wanted to add this bird to my personal collection ;) current size is 10% => 356x354 pixels
