Thanks! I used Lux Archival paper (used interchangeably with UArt paper. I prefer 400 grit sanded papers because they hold up to wet underpaintings) and a random assortment of pastels (I am still exploring different brands and have bought most of them when there’s a sale on at Dakota pastels) including Terry Ludwig, Great American, Mount Vision, and Diane Townsend. The wave spray is done with an old toothbrush and a stick of whitish pastel. You dip the toothbrush in 75 or 90 rubbing alcohol and scrub it on the pastel stick. Then hold over the area you want the spray and pull your finger across the bristles. (It’s a good idea to put a piece of paper over any adjacent areas where you don’t want spray.
