Okay, I just noticed something. You're going about it all wrong. Do one row at a time. 1 up, 1 across until you get it as long as you want it. Then put the next row together the same way only start 1 across, 1 up until you get the same number of pieces. Then when you get two rows made like this you can sew them together matching your seams. Do you follow me? If not, I'll do a couple and take pictures and show you. Also your seams should start on one side and end on the other.
