I have to agree with Laura "Valentangle" is an awesome word. I drew a heart last week and posted it. Now given the prompt of valentangle I could not get Aquafleur tangle out of my head so I did several different tiles instead of designs.
Red pigma micron on original Zentangle Tile
Brown Pigma Micron and white charcoal on Renaissance Tile.
Shading with prismacolor Terra Cotta.
Sakura Gelly Roll Clear Star, Red Star and White pens on Black Tile.
