When I quilt a project I bring threads to the front at the start places and tie them three time and thread a needle and bury the threads in the batting with the tail being the length of the needle I use. In a lot of cases that tail will be crossed with stitching with the next line of quilting. When the quilting line ends up at the edge and will fall in the binding I back-stitch and go right off the edge to save time. I know that it is secure and not unsightly.
