If you are trying to place a diamond shape onto a wide border, it might be easiest to applique the diamonds on. If you are trying to piece it into a border then you need to add background fabric triangles to the 4 sidess of the diamond to make it a rectangle and then sew your rectangles together to make a border. Take a look over at www.quilterscache.com/ quilt blocks galore to see if you can find a quilt block or border that may give you some ideas.
