merrylouw gave you some good points. Each separate square must be as near as possible to the correct measurement. If you are out 1/8 inch over 8 squares your quilt will be out by 1 inch. While 1/8 inch doesn't seem much 1 inch certainly does.
I would encourage you to practice using your rotary cutter. Are you using a quilting ruler with your cutter? I would also suggest a 1/4 inch foot for your machine.
Measure after every line you sew and press. If your seams aren't pressed out properly this can effect your quilt.
You said you don't pin, another thing I would encourage you to do. I line up seams and place a pin on either side. Provided you have it lined up properly before you pin it won't move.
Try measuring your seam allowances. From your photo it seems you have some buckling.
This is a bit of a cliche but practice makes perfect.You said you have fun which is great. Just don't ever give up.
