Distress Oxide Backgrounds with black and white lines added

The same backgrounds I just posted, AFTER adding black and white lines with an old hotel card. Sorry the lighting is a bit different. I took the plain photo yesterday and the lines today.
Black lines - distress ink in Black Soot
White lines - Liquitex Titanium white acrylic ink (liquid ink in a bottle)

I love how on the watercolor paper the white lines pick up some of the color underneath.

I like the backgrounds better with the lines added.
