So I have read some stuff about how to do this, including using a carpenter square which I have, but I am not sure how to go about doing it. I have some pieced blocks and some that are appliqued and I intentionally did the appliques bigger than needed - so how do I square it up and have the applique be centered? I don't know if I am making sense - I am very new to quilting and am not sure on a lot but you all are so very helpful. Thanks in advance.
