Take a look at the front of the block and see if there are any paces where the way the seam alloance is laying will show through. Most of the time it won’t once they are pressed flat. So, unless those every which way seams are undeneath a very light colored fabric and will show through, I’d just get them as flat as possible and call it done. If you need to change the direction for some inorder to get the block to fit into a row, you caneither let the seam twist somewhere in the middle and then iron that flat (a hot iron and plenty of starch will do the trick), or you can clip the seam allowance where it needs to twist (just be careful not to clip the seam itself) so that each end can be pressed in the direction it needs to go for easier joining to the next block
when I have blocks that are a mess of seams i generally let the seams go where they want and use lots of starch to get them good and flat. If there are some places where many seams come together and create a lot of bulk that won’t flatten even with the iron and lots of starch, then I lay it on a board and give it a couple of whacks with a hammer which usually does the trick.
Once the seams are flattened, I give it another good press from the front. I do all my own quilting on either a domestic machine or my sit down Sweet Sixteen and have never had any prblem during the quilting process when a top has seams treated this way.
In my experience, unless there are dark seam allowances pressed toward very light areas, youkd never know that some seams were twisted once the quilting is complete.
