Here is a picture of a flannel rag quilt I did. I made the batting, which was warm and natural an inch smaller than the fabric and used a 1/2" seam. I sewed an X across each block before sewing together. Because this is flannel with batting, it is a very heavy and warm quilt!
Oh and welcome to the board justme!
