Do you have a special panel that has been waiting for just the right border to set it off?  Simple straight lines with a tiny accent will keep the focus on the center. As the lines flare longer toward the outside edge, a fun bit of perspective appears in the corners. It also looks great with horizontal panels or centers. Diva 4 has the border instructions for panels that are 24"x 44", 36"x 44" or yardage.  The quilts finish at 38"x 58" or 50"x 58".
