watercolor on Arches watercolor paper 8 1/2 x 9 1/4 inches A photo taken at Joshua Tree National Park was my reference for this painting. The needles were painted using alternating layers of mask and washes, a technique I had been wanting to try with cactus for quite some time. Just finally got around to it! It turned out beautiful...and as always, is more vibrant in person. I may do some more of these--just too much fun!
