Draw a horizontal line parallel with the bottom line or edge of paper, passing through X, the top of your perpendicular line, and on it mark the points C and D the same distances as they appear on your plan.
From X on the bottom line, with B as a radius, strike a quarter circle from the line, and repeat on the other side with X as centre and A as a radius.
With A as a centre, and one-third the distance from A to X as radius, strike an arc to intersect with quarter circle A at point A1; and from point B, with one-third the distance from B to X as radius, locate point B1 in the same way.
Rule from B1 to X and from A1 to X on the bottom line, and from C to A1 and D to B1, which gives us the general outline.
The bottom lines must be rounded as dotted lines indicate, with greatest swell one-third of the distance from point X on each side; and the raking lines at the side must have the allowance added for trimming off three inches at top and bottom, hollowed to one and a half inches at centre, dotted lines, Figure [6].
Cut out along curved lines on sides and bottom, and straight line at top, and the pattern is complete.
Spread out the goods on the table face up, the pattern, if any, running from you, and the nap, if pile goods, running toward you, with the end of the goods, which must be square, even with the side of the table, in front of you.
Lay the pattern on it with the perpendicular line X——X positively at right angles to the straight end of the goods and parallel with the selvage.
If the width of the goods is not sufficient to cut the festoon without piecing, lay the pattern so as to leave an equal projection beyond the selvage at each side.
If the amount to be pieced out does not exceed six inches, make the join at one side only, and piece out with the pieces left from the raking sides, F——F, Figure [6].
