I finished a new design for my Spoonflower shop and I ordered a fabric sample and the repeat is good so its for sale now. You can buy some here:

I'm hoping to do it in colors at some point, when I figure out how. Its hard to get colors to repeat because then the whole edge has to match and not just a few points where the lines cross over. I got the edges to line up on this one by lining up the pixels in MS Paint. Of course it is hand drawn but I use paint for necessary touch up and for the edges of repeating patterns like this.
