Celtic knot

Last time I get bak to draw Celtic knots. For all those years when I didn't do that, I even forgot how funny it is. Good to be back.
Any better ideas for cathegory of this one?

!!!COMMENTS PLEASE!!!

Thank you.



I give permission to use my art.

They have the rule to educate people about Celts and about what's Celtic in my works, so here is the explanation.

This is my own variation about Celtic knot.
Celts painted knots on their skin before battles (they usually didn't even wear any trousers, because it wouldn't allow them to be as fast, as without clothes). Also they were decorating their houses and stuff with knots.
Later monks were drawing Celtic knots in books they were rewriting.
