On NGS group, we're doing a study of Darlene Olivia McElroy & Sandra Duran Wilson's book "Surface Treatment workshop" This week we're looking at the section "soap". Soapy water in a spray bottle is used as a resist. Mix about 1 tsp of dish soap in 1 cup of water in a spray bottle.
This is a "fussy" technique. The authors state that both timing and paint consistency are the keys to success with this technique. I did have some difficulty with these.
Brush on "fairly wet" paint over the surface (I used watercolor paper).
I think I didn't let the paint layer dry completely as the droplet area is not distinct as in the book.
Another way to use the soapy water is over a layer of paint. Painted watercolor paper with turquoise Lumiere paint, and let dry. Then painted over the surface with wet purple acrylic paint.
This time, I dropped large drops of soapy water over the wet paint and when the paint layer was dry, and the soapy water still wet, blotted with a paper towel. This time you can see where the soapy water acted as a resist.heated oil pastels background that had words stamped on with black Archival ink and let dry.
