It is how my mother quilted and how I still quilt bed size quilts. Recently, because I live alone,I discovered how to rollup the sandwiched quilt without help from someone or losing the tautness, This is providing I started on one end of the quilt. I use another board and two more C clamps. I do not undo any of the corner C clamps but add this new board mid section or the position I want to roll to, then fasten with C clamps, then loosen the area corner clamps on the quilted end and rollup and secure again. then remove pins on the sides enough to roll. Roll up and tighten up again. I can either remove the center board since all four corners are secure or leave it depending on how much space I have left myself to quilt. It is so nice to be able to do this unassisted. I am blessed to have large rooms with tall ceilings to set up a frame like this in an old Victorian house.
