Hey Rob,
I created something that looks a little like your draft.
I used lines and one hotspot in the bottom right, the pink linework next to it is the resulting fill.
The 'trick' is to break up your pattern in to a little 'rectangle', rather than a bunch of staggered bricks. Think of it as cropping a picture of the brick bond to get a repeating texture.
I have no idea where the line is coming from either though...
Hope my method helps you!
