If the knees or elbows on worsted wool garments become shiny from wear, try steaming them; hang them in the bathroom while running hot water in the shower.
To prevent sheen, always press heavy cotton, wool, acetate, rayon, linen, permanent-press, and dark fabrics on the wrong side. Or use a pressing cloth.
To get a high sheen on polished cotton, add half an envelope of unflavored gelatin to the last rinse.
