We used two different drawing tools (pencil and pen), one tool in each hand. I like the organic flow of the lines. Others selected a colored pencil or pen along with a black drawing tool. The possibilities are endless. One can work with each tool parallel to the other or in different directions. One side of the flowers was drawn with a pencil and the other side with a pen. Later, I shaded in some of the areas. This exercise helps use the right side of the brain more.
