I am a pretty lazy cat, if I can find an easier way to do something I will... Hence my lazy binding.... One sew, basically one really long cut and you should have enough binding material to go around any quilt.
Layer back fabric, batting, and quilt top together, baste, and quilt. Square up edges.
Cut and sew enough binding to make it around the quilt. I used my new favorite Lazy Cosmo Binding way... Sew on the binding, finish, and enjoy!
