In Diagram 1 we show how the collar

In Diagram 1 we show how the collar should be drafted for the regular three-button sack:From A to B is 1 inch.Now draw the crease line down from B to the first button hole and extend the line up from B.Lay the back part to the shoulder, edge to edge.Now measure the width of the back part as fromA to C and apply this amount out from B to D plus 1/2 inch.D to E is 1'1/4 inch for the stand.D to F is the width of the collar desired.Shape from E to A, from E to F and F to G.In Diagram 2 we show how to cut the collar for a two-button sack:Draw the crease line as explained in Diagram 1 or as shown in Diagram 2 by the thin line.For the two-button sack, draw a line from H down to the second button hole as shown by the heavy line and up from H.l is located in the same way as explained in Diagram 1.Now divide the distance between I and 1 into three equal parts.Take 1/3 of this amount and apply same from K to L and shape gorge and front as shown by the dotted lines.M to N is the same amount as from K to L.Shape the armhole as shown.O is 1/3 the distance from I to J.Shape the crease line of the collar from O to H as shown by the dotted lines and draft the collar as described in Diagram 1.In Diagram 3 we show the one-button sack with the crease line drawn to the lower button hole.The collar is drafted in the same way as in diagram 2.Divide the distance between 2 and P into 3 equal parts and advance the shoulder points 1/3 of this amount as from R to S.Now shape the gorge and front as shown by the dotted line from S to T and T to U.V to W is the same amount as from R to S.Shape the armhole from W to X.In all cases where the shoulder point has been advanced it is necessary to work in the front as indicated in the armhole.
