This is my favorite technique to-date. I am one-handed, so this will be short. Read about tech. in art tech. group. I saw it in the latest Somerset Workshop.
140# cold press wc paper, left-over coffee all over. Instant coffee with little water so thick and gooey. Random blotches - let pool. Dry. Instant coffee sticky and glossy when dry. Paper stuck to table where I overflowed edges. Dry brush off-white latex or house paint.-flat or satin. I got sample sizes at Menards. Pittsburgh brand 2 oz for $2.98 each. 2 oz goes long way. Random dry brush heavenly blue, dark sage, and chocolate turtle in diff. spots. Use damp paper towel over surface to blend. White gesso wash all over. Dab off excess with paper towels. Done. Let dry.
I am going to try again with text glued on diff. places randomly.
