1. new foam to burlap covered springs - did anyone build up the edge wire with cotton? 2. gluing the foam to the buralp - should the front portion be "pushed" down and held in place for glue to dry? 3. Has anyone used seat covers from PUI? Should I have special pieces of fabric with wire for hog rings(under side of cover) to foam and to wire on springs? 4. Should I cover from front bottom to back?
