When I learned about this, it was called furling. We were making 4-patches for a Jacob's Ladder. I thought it was a good idea, but one of our members, a long time quilt teacher and owner of a shop, said she was afraid the seam would pop open. I don't think it would if you don't cut off those threads. I saw one video on here that showed cutting off the loose threads on both sides. I would never do that.
And I seldom have to loosen threads. I just twist the two seams and they pop open. So fun.
