Playing with lines

Playing with Bias binding or bias strip is fun. The task is to take an image or a line drawing and create a linear design using thin strips of bias binding. I LOVE stain glass windows so.....off to Google Images and the following image caught my eye.

 

This is the result...It is almost complete - I need to stitch the strips to the backing fabric either by hand or using the blind hem stitch on my machine (Help?). Would you believe it? I don't have any black thread.
