Arlajo, that's the way I do my sandwich. Have also pinned backing to wall, using spray for batting and top. If the top is lap sized or under, works very well for me.

I like the Mettler Web Bond 101 spray.

This was an excellent video on how to sandwich any size quilt.

Thank you for all your advice and ideas. I knew you guys would come through. I spread out the quilt on the ping pong table top, clamped it down and did 1/2 the quilt at a time, working from the middle to the end. Seems to look OK. We will see as I start quilting.
So glad to have you all as a resource.
