I'm a fan of the pin, especially for adding borders. Find the center of the border, the center of the side of the quilt and place your first pin there. Now pin at the beginning and end of the strip. Then through out the strip every 5 or 6 inches. Sew in place.
One more tip and this was passed on to me from Diana, my work buddy. These little bobbin washers have really helped me with my quilting.
Along with always ALWAYS adding a drop of oil when I change bobbins these little babies have really made my sewing life a bit easier.
