I recently purchased Corel Draw, a graphic design program. The learning curve is pretty steep for me, not being very technologically savvy. So I've been playing with it and drawing strings for tangling, as well as designing Zendala templates. Here is one of my designs that was pretty easy to do... just circles and ovals... from which I then deleted some portions of the lines.
Patterns Used: Beelight, Fassett, N'zeppel, Tipple, Baton, Frosty, Sand Swirl, Arukas, Crescent Moon, Knot Rickz, Antidots, Podzles, Maryhill
Then I added the blackened parts. I didn't do that originally because I had decided I was going to try adding color later and didn't want the black spots to interfere with my coloring. It's starting to look better here.
Now with the shading it looks much better!
Next I printed a copy to color. But I decided to start with the drawing that has the parts blackened in, rather than pre-blackened. I used chalk pencils to add the color, which, as usual, blended really nicely. Unfortunately, whenever I scan my work it's hard to capture the colors just the way they look in reality. Some sections here look a little washed out.
I like the color, but the black and white shaded one is my favorite. Black and white is what drew me to Zentangle in the first place, and generally wins out over color in my mind... but not always!
