Binding: Do not iron the binding in half lengthwise before attaching it to the quilt. That is my best advice.
Hanging sleeve: Make sure your sleeve sits on the quilt in the shape of a D. The flat part of the D is up against the back of the quilt, and the rest of the sleeve should not sit flat against the quilt. That way when you hang it, the quilt will hang nice and smooth, and won't bulge out in front of the hanging rod.
