How about this idea (remember I am new to quilting) - but for knotless hand embroidery and hand sewing, I use say a length of floss/tread 20 inches long, double it over so it is 10 inches (sewing with double thread) and instead of threading the "loop" through the needle, thread the two tails through the needle, leaving a "U" shape at the bottom. Insert your needle through the quilt top and batting (not the back yet), leaving a loop of thread on top momentarily, bring your needle back up and then through the loop and pull it tight - you now have a secure stitch to start with and no knots to pull through anywhere. I use it for all of my hand sewing, including buttons, and embroidery.
