The inner border is not supposed to be solid and I wasn't planning on mitered corners, but I'm not worried about that. Mainly I just want to see if my sizing works. I think you got the sizing right. So nice work! :)
Hmmm...the inner border seems a bit too thin. It might be my sizing or it could be you put it in a solid color. Do you think you could post a copy without the color? That way I could put it in the colors I chose and see if it changes anything.
