I've buried threads in the past, but with my ADD this made me absolutely crazy. I've decided for non-competition quilts, especially these first few that I'm learning on, I'm going with the method of pull the bobbin thread to the top, make 1/4 inch of micro stitches, clip the threads, then move on to a more regular stitch length. For ending, the technique I learned this weekend is similar - 1/4 inch of micro stitches, then move the quilt over (~1/8-1/4 inch) and tug on the top thread to pop the bobbin thread up - and trim the bobbin thread loop (no need to pull much of the bobbin thread up - just enough to clip) and trim the top thread. That way I don't have to did around under the quilt to clip the bobbin thread.
I'm sewing mainly on my Bernina 830 Record and don't have a backstitch.
Cheers, K
