Recent Zentangle tiles

For the next few weeks there will be no new Zentangle challenge from the Diva on Mondays. She's taking a much-deserved family-time break until January 9. That will be a different sort of challenge for many of us!

I've decided that on those Mondays I'll post a few of my interesting, and relatively recent, Zentangle tiles. Herewith the first installment: two tiles with some spaces left empty and a monotangle.

Tangles: Assunta, Black Pearls, Dutch Hourglass, Lilypads,
Lotus Pods, Ogen, Prestwood, Yale, and something
Jane Monk does that I really like!
(I'm considering filling that white 'wing' on the left to make
an egg shape stand out more.)

Tangles: Assunta, Black Pearls, Crescent Moon,
Finery, Meer, Shattuck, Tripoli

The tangle here is based on something I saw from Bettie Lake, with
intertwined black and white ribbons and a few little circles/beads/bubbles.
I really like it, but I don't know if it has a name.
The string is Sue Clark's brilliant Tri-Shapes string (circle/square/triangle) idea.
Hard to tell when the tangle doesn't fill the entire space right to the edges!
