Here's what I did on a baby quilt.
I pulled up the bobbin thread by lowering my needle once and bringing it back up with my 'needle up/down button'.
I went two stitches forward and two back and then sewed.
After I quilted the entire thing, I sat in front of the tv and buried the long threads into the quilt and snipped the ends.
Is this the correct/best way? Don't know - it's what I did for a baby flannel quilt that was not going to be judged...just loved.
I agree to take your time using the walking foot...let it do the work.
Check the back occasionally.
I reminded myself (and sometimes out loud) that I was quilting faster than hand sewing...so relax and enjoy the process!
