Q: When I see fabric rated at (3.5 OZ) as in CECONITE 101, does that mean it weighs 3.5 oz per sq.yd.?
Yes, the fabric listed weight is per square yard.
Q: Regarding Ceconite Fabric Uncertified Lite: Is this price per square yard or is it 72" x 36"?
This is priced and sold by the lineal yard, so it would be 72" W x 36" L for qty 1.
Q: Does this fabric shrink with heat? I want to use it on a RC airplane.
Yes this will shrink with heat.
Q: Does this fab need dope to stick, or is it already coated so you just iron on and then shrink it?
