What kind of batting did you use? I've always left about that much batting on the outside edges, have not had a problem with fuzz from it and I've quilted on black where it would have been readily apparent (used warm & natural cotton for that one).
Also, do you plan on washing the quilt after you bind it? That will help remove the lint. Eventually if it's just fuzzy lint even the lint under the stiches will come out on it's own.
