I have a quilt frame and I use muslin to cover the poles so I can attach the quilting fabric. I take one piece of muslin and fold in half that is the width of the poles plus 3 to 4 inches, double that. Now put wrongs side together, seger the edge together, turn and sew a seam the width of the pole. This makes a casement to put the poles in. Then you pin the qulting fabric to the muslin and you are ready to go. I layer all my pieces and then roll.
I pin baste from the center out both ways and it works great.
