I didn't know that pattern and googled it - wow - what a beautiful pattern!!!
The one that I looked at was all these squares put together - you could cross-hatch it. I also do a lot of echo quilting. Depending on the size of the block, I might come in only 1/8th inch and just eyeball it..
You could outline the different pieces - like outline the chain that goes around. Don't forget to look at the bigger picture.
