Here are some of my diagonal patterns. I had trouble with the loopy line. I aligned it properly to the diagonal line, but I could not make the joint smooth no matter what. It might be because of the way I drew it originally, but I a not sure. So I pasted a colored blob on top of it and I am going to say this is the design :). I'll use these as is and also as a background and layer other elements on top. Thanks!
