When I took a FMQ class, the teacher told us to set the stitch length to the smallest the machine would go & then take 4 or 5 stitches in place. Then change stitch length to quilting stitch. Do the same at the end of your quilting line. It works well for me. I haven't had to fight with or bury those threads since. My machine has an automatic thread cutter so I only have to trim a short length of bobbin thread on the back. Just clip it close to the quilt. Hope this helps.
