The only other addition to my brush collection is a well-used toothbrush for spattering techniques. It takes time to mould a toothbrush to spatter just the way you want it to. I spatter at an angle onto wet or dry paper, which gives me wonderfully unique results. Spattering onto dry paper will give you neat dots of color, while spattering onto wet paper will allow the color to fuse softly with the water. Try spattering onto wet paper. Allow this first application to dry completely then spatter again onto dry paper with the soft fusions from the previous application of dots acting as a backdrop. The results are beautiful.
