I had the same complaint last week! lol I worked so hard to make the pattern even when cutting I couldn't figure out why it was so crooked when I started piecing them together! Then someone asked if I ironed instead of pressed. Ironing stretches the fabric. It really does! I'm pressing on the project I'm working on now and what a huge difference! Who would have thunk it? Don't know if this applies to you but it's worth a mention.
