The Butterfly Affect- Watercolor & Marker on Vellum

For this experiment I pasted a heavy sheet of vellum onto white mat board.

I drew my composition in black fine line marker and painted loosely with bright watercolors.

After it dried I used the point of a fresh exacto knife to scratch out a pattern.

Because the vellum has a coating on its surface, it is very easy to scratch away on.

I also picked out some highlights in the firey sky.

The results of working the vellum surface in watercolor looks much like YUPO paper.
But I don't know if you can scratch out on YUPO.
But I'll find out as that is scheduled to be one of my play pieces.

This is a very quick painting, about two hours, but the process expanded on could be useful in the future.  Maybe with more rich, darker coloring as a reverse scratchboard.

Now I'm thinking maybe this would work better on clayboard and I've been wanting to
try alcohol inks.
Humm.. maybe I do need a few more art supplies!
This is virgin territory and I don't know what I'm doing but keep moving forward.
