Lots of good tips here when pressing the seams open...shorter stitch length for sure and a new one to me is using wonder tape to keep the intersections from moving since you can't nest seams that are pressed open.
I was wondering if anyone does both methods of pressing the seams open and pressing the seams to the side within the same block? We had a block exchange and I saw a block done this way. It looked fine in the quilt, once backed with batting and backing and quilted.
