I've done all of the above. Now for a really nice quilt I use wonder clips and hand stitch the back
For a heavy use utility quilt, I use elmer's and machine stitch from the front.
Since developing arthritis in my thumbs, it's easy use for the thumbs and never do it with just fingers.
Also, since getting older and still having way too many to finish in my life time, it's the fastest way possible.
My happy part of the quilt is the design. Finishing is the grunt work.
