If you subscribe to TheQuiltShow.com, Linda Taylor has a series of classes for how to load and use your long arm. Her method of pinning on a quilt is so sensible and quick, that alone is worth the price of the subscription.
Short explaination: Start in the middle of the quilt edge. pin out every 4 inches. When you get to the edge, go back putting a pin between each of the previous pins. When you get to the middle, go to the other edge placing a pin every 4 inches. Go back to the middle putting a pin inbetween each pin. She claims you can have a king sized quilt loaded in a half hour. She is right. So simple, but it organizes you and you don't take extra time to figure out what comes next.
Hope that helps some.
