Doing something similiar here to, been looking at wall design and found that oakislandgroup.com carries a fabric that can be connected to wood and or I was thinking doing a pvc or metal frame. It comes in rolls that will cover 75 4x8 walls for 750.00. It is paintable and is fire retardent. Not sure where it is on thier website but was refered to them by a professional freind haunter up in the Seattle area. Not sure if it helps much but looks to me to be the best bang for the buck and using the pvc or bolted pipe would make for easy storing.
