Yes, I have done it on a friend's quilt and just did it on a quilt I was making for my neighbor. I had the quilt about 3/4 done and did not look the way it was looking - so I ripped out all the machine quilting and started over. Much more satisfied with the second round of quilting. Also, ripping out the stitches is something I can do in front of the TV - can't stand to 'watch' TV without some kind of hand work.
