More triquetra strings

Last week I showed some Zentangle tiles using a simple Celtic knot triquetra as a string in this post. At the end I said I'd try some more intricate knots, so here goes!

The triquetra is often done with an added circle, so I tried one of those.

Tangles: Black Pearlz, Beadlines, Fleurette,
Knightsbridge Aura, Ragz (with Rounding)

I also did one without doing 'bands', just the triquetra to divide the space.

Tangles: Flux, Providence, Purslane (a Flux variation),
Tipple, Tripoli (3 versions)

Here is the basic triquetra with an added loop in the middle.

Tangles: Black Pearlz, Camelia, Cruffle, Pearlz, Tortuca
