I have always used the method that Sharon Shambers uses---boards and baste.. There is a video specifically for hand quilting. You will find it on you tube. It keeps all wrinkles out of the backing and works wonders!!
Then I do use a 24' hoop to quilt my quilts. It is a little more work to get the quilt ready for hand quilting, but saves so much frustration in wrinkles in the backing...
