For this mixed media painting I used Texture Medium by Winsor & Newton. I have applied it to the entire surface of the petals and selectively in the background. The petals have got a grainy and rough surface. The spots are more visible because they have pushed the watercolor around them. With ink, I then emphasized the edges of the petals and the inside of the flower so that they can stand out better from the background. I promised myself more from this texture medium. It takes a lot of it to get a texture.
By the way, I opened a 2nd channel. In case you are interested, come and take a look at it.
