A first for me

This is a customer quilt.  She wanted 60 degree diamonds in the border.  I am sure there must have been an easier way to accomplish this, but I wasn't able to figure it out.  It was difficult to make it work out when I went around the corners.  I struggle with marking light fabrics.  I have heard horror stories about marking pencils, so I only use school chalk.  I did freehand leafy design in the middle and did SID on the skinny border.
