I printed my black and white zentangle drawing on marker paper and colored it with alcohol markers. At first it was a bit to garish with too much contrast, so I painted a warm grey over the whole piece. That gave me what I was looking for. Of course, THEN I completely undermined that with making a bunch of wild colored ones (two shown here) by playing with them in Photoshop. I shall be using this (along with my Zentangle koi posted la while back) for printing blank cards that we sell for charitable (mostly foodbanks) organizations.

Freehand sketching in ink from a photo reference I found online, to practice conveying that lots-of-stones look without drawing all the stones (photo credit: K. Mitch Hodge). Micron pens + alcohol markers.
