Seams!!!!!

Which way do you press the seams on blocks that have many pieces? There are multiple opinions on how to answer this question. I have read, watched tutorials, and asked other quilters what they do when it comes to pressing seams. One of my friends said to just press the way it fits best. Well, this is difficult to do when there are eight rows of  eight inch blocks made from four inch blocks made from two inch strips! The Tannenbaum tutorial by Jordan Fabrics, recommends pressing the seams to the dark fabric. Donna Jordan demonstrates that pressing correctly, even on seams that are going in the same direction, will solve the problem and result in a flat seam. I had to do this on some of the pieces and they did come out okay. One of my friends recommended pressing the seams open.  I did a little bit of both…open and to the side. There were still places that I had to redo in order to make a flatter seam. I am happy with the accuracy of my quarter inch seams. This helped a bit, but it was still a hassle.
There has to be an easier way. Any tips or suggestions would be appreciated.
I finished piecing the center of the Tannebaum quilt top. I do not know if I will add just one border to make it a throw size quilt; or three borders to make it a queen size quilt.
