CHAPTER X UNITS OF MEASURE AND THEIR APPLICATION What is the unit of measure for cloth, ribbons, silk, etc? Why is exact measuring of great importance to the employer? To the customer? To the employee? 67. How to measure goods. Goods should be measured right side out, the loose threads being left on the right side -not on the wrong side. Use the yard stick with the inches marked on the outside-not on the back. 1. Double width goods should be measured on the fold: flounces, laces, etc., should be measured on the selvedge edge: avoid stretching. 2. One and one-quarter yards make a fold or an "awn." 68. Dress goods. Directions for measuring dress goods accurately: 1. Gauge amount of material to be unrolled. 2. Straighten out merchandise. 3. Hold the length of the goods firmly with the thumb of the left hand on the end of the yard stick, and measure to the next yard with the right hand thumb. 4. Place thumb to thumb, and measure the next yard, etc. Make no allowance for damage in goods, unless under proper authority. 5. In cutting dress goods, use filling threads as a guide to avoid waste.

How would such knowledge be of service to you? Would it add to your value as an employee of a store? How would it help a customer? 69. Carpeting. Rugs are sold by the piece; all other carpeting is sold by the yard from the roll. Carpeting is usually 27" wide (Brussels or Wiltons) or 36" wide (Ingrains). Linoleum is generally sold by the square yard. 1. The number of yards needed for a given room depends upon the way the strips are to run. There may be more waste if they are laid one way, rather than another; that is, lengthwise or across the room. There is waste in matching; as in wall paper, a fractional part of a width cannot be bought. 2. To estimate the number of yards required to carpet a room: determine which way the strips shall run and estimate their length and number; add to the length of each strip after the first allowance for waste in matching. The combined length of the strips in feet divided by 3, will give the number of yards required to cover the floor. Problems (1) Measure your schoolroom floor and determine how many yards of carpet 1 yd. wide it would take to cover it, placing the strips lengthwise; crosswise. Which is the more economical way of laying the carpet? (2) What will it cost to carpet a room 16 ft. long, 12 ft. wide, with carpet 36" wide, at $1.19 a yard? (3) The price of linoleum is $1.75 a square yard. What will it cost to cover a floor 12 ft. long by 10 ft. wide? (4) How many yards of carpet a floor 19 ft. long by 17 ft. wide? $1.12 a yard? yd. wide will it take to cover What will the carpet cost at (5) How many yards of carpet 27" wide will be required to cover a floor 9 ft. by 12 ft.? What will the carpet cost at $1.20 a yard? (6) Estimate the cost of carpeting a room 16′ 2′′×12′ 4′′ with Brussels carpet, at $1.55 per yard. ILLUSTRATIVE EXAMPLE (1): Find the amount of carpet and of border that you must buy to carpet a room 15 ft. long and 10 ft. 6 in. wide, with carpet 27 inches wide, the strips running lengthwise and the carpet having a border of a yard wide. = Solution: 15 ft. 5 yd. 10 ft. 6 in. =3 yd. 5 yd.—(2× yd.) 14 yd. =33 yd. the length of each strip. |
