I did this piece for my daughter-in-law's birthday. She is all about calla lilies. This is an 8"x16" canvas with acrylics, paper and pen shading. I learned a new technique for this painting - how to shade with Faber-Castell PITT artist pens. These are ink pens (in fabulous colors) and you have about 20 seconds to smudge with your finger tip to get a blurry shadow. AHA - I discovered you can also use a wet brush and softly blend and shadow. I love shadowing and now have a new love for these indispensable pens.
