Twisted seams are not major in my book, but I like patterns that say which way to press the seam.
Making furled seams, sometimes called spinning the seams, helps a lot. All seams nest that way.

When I taught my stars class, I had students press each seam as it was made: with background to your left, press away from you. When all seams are finished, your iron will spin all the way around the quilt block. All seams will be the same way around the circle. Then twist the very center of the last seam so that each half goes the opposite direction. They have to follow the direction of the other seams. Mush that center down very well and you will have less bulk there. A rubber hammer works, too.

Now when you add border or sashing, all those seams are the same way. Sew with them pointing toward you so they don't flip the wrong way.

If you sew these blocks together without sashing, all seams will nest.
