1. A METHOD OF MANUFACTURING A COLLAR TOP OF A TWOPIECE COLLAR COMPRISING THE STEPS OF (A) CUTTING OUT A FABRIC BLANK IN THE FORM OF AN ELONGATED STRIP OF FABRIC HAVING A MIDDLE PORTION AND TWO END PORTIONS OF SLIGHTLY LESSER WIDTH THAN THE MIDDLE PORTION, SAID BLANK BEING SHAPED SUCH THAN, ON BEING FOLDED ALONG TWO SPACED LINES ACROSS ITS WIDTH AND ON ITS ENDS BEING JOINED, A COLLAR-SHAPED ENTITY IS PRODUCED WITH THE LINES OF THE FOLDS CONSTITUTING THE FRONT EDGES OF THE ENTITY, (B) FOLDING SAID FABRIC BLANK ALONG SAID TWO SPACED LINES ACROSS ITS WIDTH, TO BRING ITS END INTO CLOSE PROXIMITY, AND TO SUPERIMPOSE ONE EDGE OF THE END PORTIONS ON ONE EDGE OF THE MIDDLE PORTION WHILE SPACING THE OTHER EDGE OF THE END PORTIONS FROM THE OTHER EDGE OF THE MIDDLE PORTION, (C) JOINING THE SAID ENDS BY A ROW OF STITCHES, (D) JOINING SAID SUPERIMPOSED EDGES OF THE SUPERIMPOSED PLIES OF THE THUS-JOINED STRIP ALONG THE LENGTH DIRECTION OF THE STRIP THEREBY FORMING A SEAM, (E) TURNING THE ASSEMBLY INSIDE-OUT, (F) SUPERIMPOSING SAID OTHER EDGE OF THE PORTIONS ON SAID OTHER EDGE OF THE MIDDLE PORTION THEREBY DISPLACING THE JUNCTION LINE FORMED BY SAID SEAM IN A DIRECTION IN WHICH IT WILL BE OUT OF SIGHT ON THE INNER FACE OF THE COLLAR TOP, AND (G) JOINING SAID LAST-NAMED SUPERIMPOSED EDGES
