When I start quilting I push the button to take the needle down, push it to bring the needle up, crab the top thread on each side of the little dip and pull it up, it brings the bobbin thread up and I take tip of the scissors and pull the bobbin thread to the top. I stitch a stitch forward and backward to lock the stitch and continue on my way. I then cut both threads close to quilt and it never comes down, I end the same way. Make sure you don't try to start where there is a seam allowance, it won't work, too thick . This way always works for me.
