headliner is the 'foam' used as a headliner (roofing) in cars. It comes in beige, grey and black at JAF and runs about $15 per yard (54" wide) regular price. It is a not a fabric so fabric cut coupons can not be used. But, a coupon on regular priced item may be used. It is a bit 'more foamy' than the stabilizer, but should work in most places interchangeably.
