Welcome from NE Wisconsin!
My suggestion is that you go to your local library and find a quilt book with "easy", " quick" or "beginner" in the title. I'm not saying that you can't make your design, but that you will find a lot of tips for a new quilter. The advice you have been given above about figuring the scale of you blocks on the graph paper is right on.
Don't hesitate to come back with your future questions. The group around here is very friendly and experienced!
