black grommet valance

Most black grommet valances are 100% polyester. Fabric constructions noted include woven (plain weave) and sateen twill.

Most are machine washable. Care instructions (from one listing) recommend machine washing cold with like colors on a gentle cycle, using only non-chlorine bleach when needed, tumble drying low and removing promptly, and using a cool iron if needed.

Descriptions include triple-weave fabric technology as well as plain weave and sateen twill woven constructions.

Guidance in the listings recommends a valance width about 1.5 to 2 times the window width for proper fullness. (One example listing shows a 52"W x 18"L valance.)

They’re described for kitchen and dining rooms and are also mentioned for bathrooms, basements, RVs, and general home decor use.
