I love this.  I am learning to paint and design with alcohol inks.  The paper here is Yupo paper, which is a plastic, non porous material.  The background medium is alcohol inks.  After drying, I used the alcohol inks as my string for drawing the outlines of the flowers, stems and pedals.  Using a sakura micron black pen to fill in the flowers with Zentangle patterns.  I still need a lot of practice using the alcohol inks.
