I heard it called
Stab Stitch quilting, but others have referred to it as Pioneer stitch. You use embroidery floss or some other thick corded thread so you really SEE the quilting. You make large stitches, as large as you want but typically you are getting only 2-3 stitches per inch. Just like tied quilts, these large stitch quilts will not last as long if they are frequently washed, but they are warm and cozy. I use a thicker batt for it, although I believe traditionally, they simply put an old blanket in the center and quilted over it. You need a SHARP needle and a thimble. It's not really that much different from sashiko, only you use colors instead of either white or black.
My great-grandmother's last two quilts were done using a stab stitch method as she was nearly blind. They still stayed together until recently and were made in the 1940s.
