Two things come to mind.
Suggest you research "Zentangle" drawing technique first.
Second is your skill at freemotion quilting.
I would also try to find the book and flip through it before buying.
Zentangle is a "doodle" type of pencil or pen drawing. It is gaining in popularity. The headquarters or home base is not far from where I live and the originators have classes and retreats in the process.
I see that quilters are picking up the techinque and adapting it to quilting. It appears to be a background type quilting but more controlled into specific motifs and shapes.
It probably would be useful if you had a class in drawing Zentangles before attempting to take it to quilting.
This is my impression. I get the Zentangle emails and newsletter and try to keep up with the technique.
