Yup, if there's one thing we're passionate about here, it's labels. Doesn't matter where you put the label - some people even like to put it on the front of their quilts but most put it on the back either on the right- or left-hand bottom corner. But then again, I've seen them on the top corners and also smack in the middle. It's your quilt and wherever you want to put your label is just fine.
By the way, welcome to the board!
