Having super flat seams at block intersections or block units, makes quilting so much easier. A few years back, I learned how to twist my seams and that was a game changer.
Way back in 2014, I wrote up a blog post on how to twist seams and it was well received. I know that it helped a lot of quilters and that makes me happy. That information is still good, but I've made a couple of changes in process. You can see the original tutorial HERE.
