I have not a lot of experience with Gouache, and had a hard time warming to the medium. So I went looking for classes to help me with this. This is how I found Alisons class. I was intrigued by the wood cut like appearance and decided to give it a try. 

After watching the lessons I started two paintings of christmas ornaments: A glass fir cone and a disco ball ornament.

It felt a bit weird pasting the color on so thick and bright, but that's what Alison said. So fine, I went along.

After letting the gouache dry thoroughly I applied the black india ink. It was part exciting and part fearfully hoping that it would really work. But smother I did. And then I stalked around my two paintings until they were dry enough for the revealing water shower. And I was so pleased! The ornaments emerged with a wonderfully grungy look, combined with lovely pastels from the washed out gouache!

I liked the effect very much and will experiment definitively more with this technique! Thank you very much, Alison, for sharing and teaching!
