About Me

My Background

My love of nature began as a child growing up in culturally rich Philadelphia, PA. There, I studied a variety of art media and the sciences, and as an adult, I combined two of my passions – Art and Nature - in both my career as a biology teacher of 36 years and as a watercolor artist.

My Medium

Now as a retired teacher and full time artist, I work exclusively in watercolors, using their wonderful translucent qualities to great advantage. Continuing my love of rich color that I achieved in the oil paintings of my youth, my watercolors are stunningly vibrant and vivid. 

My Inspiration

Florida remains my favorite place of inspiration. I focus on exotic flowers, seashells, shore birds, sea life, and delightful scenes of families making memories on the beach. I also paint still life, landscapes, and abstracts, and developed a distinctive rainbow style in my animal and sports series.  

How to Make Your Watercolors Glow - Tomatoes Painting

Here is a tutorial on how I created the golden glow on my watercolor painting of tomatoes from the supermarket. 

Create Great Backgrounds with the Cross Hatch Method

The cross-hatch method of building up layers of color results in rich, dark backgrounds. Using a flat brush that holds more paint than water, excess water can be wicked off on a towel before touching the watercolor paper. Use the same colors that are in the rest of the painting to give a unified effect. Dark colors add drama and depth, especially when used next to the lighter colors in the painting.

Why and How to Use Masking Fluid - Pretzel Salt

In this tutorial, I'll show you how to protect the your watercolor paper to leave areas white. There are other times when I want to be able to protect an area already painted while creating the background. In this demo, I'm covering parts of my paper that will be the salt on the pretzel. This is done with masking fluid. I've been successfully using Pebeo Drawing Gum, but there are a number of good products that will do this.  Please let me know if you find this video interesting and helpful. 

Mingling (Not Mixing) Watercolor Technique

Mingling is a technique used to control how the watercolors blend together without creating "mud."

How to Create Watercolor Beach Pebbles

This tutorial demonstrates how to create pebbles on the beach or any object that has a shadow. It also explains how to make objects in the foreground larger and those away from the viewer small to create a sense of depth in the painting. 

Changing, Correcting, and "Lifting" Watercolors

Even though it's usually  thought that watercolor changes are impossible, I'll show how to correct mistakes and create useful effects by "lifting." 

Rainbow Fantasy Series Creation

I show how I create this colorful rainbow animal series of watercolor paintings. One of the “secrets to success” here is to rinse the brush every time before you add another color to the still-wet previous one. Please comment to let me know if this video is helpful.

Preserving or Regaining the White of Watercolor Paper

Here are two types of masking fluid products that work well to preserve the white of your watercolor paper. After applying the masking fluid, be sure to allow it to dry totally before applying your paint. Once the paint is totally dry, the masking fluid can be removed by rubbing your finger over it and simply peeling it off or using a rubber cement pick up block. Once you've lost the white of the paper, you can regain it with white casein
