One of the things that I truly find mesmerizing is the concept of paint pouring. I started following an artist named Olga Soby some time ago and I have to admit I have a really great time watching her videos on Facebook. You really should check out her page if this stuff interests you at all. She features a lot of technique. She creates some truly stand alone pieces but part of what I find intriguing is how would this work as backgrounds for some of my pieces? I expect I will try it pretty soon. Check out here page here.
Here is one of her videos to get you started.
