This is my response to Zendala Dare #67. I love this template that you can find at The Bright Owl .
I started with one of my hand colored tiles and put the template on by tracing it with a light box. I used my watercolor paints and selectively painted the sections I wanted. When it was dry I added my tangles using colored Micron Pigma pens. I also added some shading using colored pencils at the end.
The photo below is what the tile looked like before I started to put lines, colors, the tangling and shading. I love using tiles that have an interesting background because it looks so good to me. You could probably talk to art teachers who will talk about how it 'unifies' the piece or how it 'marries' the colors. I don't know all the art theory, I just know I like it.
