i do it always no matter what machine i am using, and what purpose i am using it for, does not matter if i am quilting or hemming a pair of pants...needle down/ needle up; bring that bobbin thread to the top. that way you can hang on to both threads when you start. no 'nests' on the back, and easy to clip both threads.

Aha!! I will adopt this practice also! I want to do good work!

I can see you bringing the bobbin thread to the top just to get it out of the way, but when finishing the quilt, I would bring both threads to the bottom, knot it and bury about 2" inside the quilt. If I'm putting hard work into the quilt, I'm going to do everything I can to make sure the thread ends are secure, just as the ube quilter says. :)

Thanks Quilter7x. There is so much to consider. So, you "lock in" the stitches (back and forth a couple) and also knot and bury the thread. I want to do it right but UGH I think I'm regretting the SID on this particular quilt. Oh, well!

What I do is put the needle down and then up. Raise the presser food and then grab that needle thread and pull gently. Then a little loop will peek out from the bottom. I use my seam ripper to gently pull that loop which is the bobbin thread. Once it's up I put my fabric back under the presser foot in the correct place, lower the foot, and then sew while holding the threads (to make sure they don't get caught in the sewing. I use a stitch length of zero and slowly raise it until it's the normal length and at the end, slowly lower it back to zero.

Yes, if the distance is not too great, I do that, too.
Never thought of bring bobbin thread up at the END of the line, always do it to start.
