Notes on painting with acrylic pain: This time I used water to thin out the paint. I found that it is easier to blend this one. The con is that after the paint drys it looks very flat. Also it is easier to get smudged. So it is wise to seal it with clear gloss.
When I use extender to thin out the pain, the finishing/drying time is much longer. And the paint will look a bit shinier. But I found it hard to paint without getting it blotchy.
