wow- that does sound like a lot of work!
i never deal with any of that-
i am a long arm quilter- when i start i bring the bobbin thread to the top- hold the bottom and top thread with one hand- and take 3-4 tiny stitches- then start quilting- when i have moved away a few inches i stop and clip the threads at the quilt surface....that's all there is to it- when i am stopping i again bring the bottom thread to the top- a few in place tiny stitches- and clip---all done. I've quilted a couple hundred quilts- have not had any come undone.
