Couple of other suggestions. If your thinking no storage room for the 4x8 foam insulation sheets you can cut almost through the middle or at each 1/3 length and make a folding joint using duct tape. This way you can store at the back of a closet, under a bed, or behind a couch or cabinet. Sam's club sells reasonable folding 6 ft tables and your local library may have a meeting room with tables they will let you use when it is not booked. Joanns usually has a classroom if this is closer than LQS.
