Fabric quality inspection and pattern layout

Well I hope there's enough of this fabric now that I've had a good look at it.  This was part of a mystery bundle it a stretch cotton from Fabricmart.  It's like nothing else I have in the stash, but as I was laying it out I noticed some irregularities.  Some black circles were darker than others on the back, so I flipped the fabric over and had a closer look.

The circles on the top pic, are on the back of the fabric.  The pic on the bottom are also on the back, notice that the ones below are darker, and it's the same design repeat.

I'll do my best to avoid the light band, where it looks as if they were changing threads out on the embroidery machine because around that same area on the face, there are loose thread ends.

The front piece on the pattern is very large, so it may be difficult to avoid this area.  If it can't be used, I'll pop this back into the stash, with my notes and look for something else.

Here's how I've marked it to avoid cutting into the areas.... painters tape:)  I've marked the areas with defects, then again at the selvage so I can leave these areas as space between the pattern pieces.
