So, after I messed up the original image I started over again... By the way - this is the second time I've started this image over.
I penciled in a grid and then the initials so I would know where to tangle. Here is what I have completed so far - this is the upper right side of the image.
Close-ups of the two sides of the image so far...
I put the initials on the page and took two more pictures so you could see what the image will look like with them on it.
