I bring up my bobbin thread when I start to the top and make sure I have a couple of inches of both threads...when ending I raise my needle and move a couple of inches out and then cut my thread so I have a couple of inches left.....every couple of hours of quilting I stop and bury my threads in the middle of the quilt using a needle (betweens) and hand quilting thread and I thread both ends into the needle so I form a loop on the other side of needle.....I go into last hole with needle....just under top or bottom for about one inch and come back up.....shove the thread ends into loop and pull thru...clip where they come up....thread ends now buried in the middle of quilt
