There is a knack even in washing windows. They should be kept clean and thoroughly clear for the display of goods. Choose a dull day, or at least, a time when the sun is not shining on the window, for then it causes it to be streaked, no matter how much it is rubbed. Take a painter's brush and dust the windows inside and out, washing all the woodwork inside before touching the glass. The latter must be washed simply in warm water and diluted ammonia—do not use soap. Take a small cloth with a pointed stick to get the dust out of the corners; wipe dry with a soft piece of cotton cloth—do not use linen, as it makes the glass linty and dry. Polish with tissue paper or old newspaper. This can be done in half the time taken where soap is used.
To polish plate glass windows and remove slight scratches, rub the surface gently, first with a clean pad of fine cotton wool and afterwards with a similar pad covered over with cotton velvet which has been charged witli fine rouge. The surface will, under this treatment, acquire a polish of great brilliancy quite free from any scratches.
Select shades that harmonize, as described on Page 474. The back ground for dark silks should be formed of light colored China silk; for light silks, of dark plush. The three lower puffs are draped over small wooden racks of the width of the silk. The three center pieces are draped over drums, three feet in height. [See Page 503] The top puffs are arranged upon a rack, built up from the bottom of the window.
