You may want to study the studios of both Caryl Bryer Fallert, and Leah Day. Caryl Bryer Fallert's studio is at Bryerpatch.com. Not sure of Leah Day's website, but on each I have seen that they use ceiling mounted hardware to take the tension off the quilts they are working on. Fallert even has retractible cords mounted to the ceiling all over her huge studio.
