This is some grill cloth material I have that I use for fiberglass shapes and stuff like that. It is no longer super clean white color anymore, so its best that you use this as a building material and not a finishing material. 

Material is 68" wide and is sold by the linear yard. 3 feet long. If you order 2 quantity you are ordering 6 feet long and it will come at that length instead of two separate 3 foot lenghts.
