1. Don't use opaque Setacolor paint; only the transparent works.
2. Thin paint is best: add water in a 2-to-1 ratio. Thick paint does not produce a darker result; the migration of the paint makes it darker and it needs to be thin to move.
And I actually got some patterning--
I'm not wild about the color, but the images are clear--and that wasn't happening last summer when I tried this.
I am happy with this one, which was the result of some scrunching and some mixing of colors. Now I am ready for a project with grand-kids!
And to round out the week I dyed some shimmery silk for a current project. This just glows when I work with it.
